OGTT Test Price in the Philippines (2026): 75g, 100g & Pregnancy Rates

Quick answer: An oral glucose tolerance test (OGTT) in the Philippines can cost ₱315 at UP–Philippine General Hospital (PGH), while Medi Linx Laboratory publishes ₱370–₱680 for 75 g tests involving two to five blood samples. For pregnant patients, a 75 g OGTT with three blood extractions costs ₱480 at Medi Linx and is advertised at ₱670 through Hati Health for participating Hi-Precision branches. An OGTT may also be available without a separate laboratory payment through PhilHealth YAKAP, subject to eligibility, clinical assessment, and provider arrangements.

When it is used: An OGTT measures how your body processes glucose after you drink a measured sugar solution. It is commonly requested during pregnancy, usually between 24 and 28 weeks, to check for gestational diabetes. Doctors also use the test to investigate possible diabetes or prediabetes in certain patients. Unlike a fasting blood sugar test, an OGTT requires several timed blood samples and usually takes at least two hours.

OGTT Price in the Philippines: Quick Comparison

These are actual published prices from selected providers, not an official Philippine average. Before booking: Check your doctor’s request carefully. A 75 g OGTT with two extractions is not the same test schedule as a 75 g pregnancy OGTT with three extractions.

Actual OGTT Prices at Hospitals and Laboratories

The following examples show how prices differ among government hospitals, independent laboratories, and private diagnostic providers.

The Hi-Precision amounts above are online booking prices displayed by Hati Health, not guaranteed direct walk-in rates. Prices and promotions can change by branch.

UP–Philippine General Hospital OGTT Price

PGH publishes separate laboratory rates according to patient classification.

PGH also publishes higher rates for certain admitted-patient classifications. For example, the 75 g OGTT is listed at ₱820–₱990 across its displayed inpatient room categories. These hospital billing classifications should not be mistaken for different OGTT procedures.

If you are having a routine outpatient test, ask the hospital which rate applies to your registration category.

Medi Linx Laboratory OGTT Price

Medi Linx Laboratory publishes a particularly useful breakdown based on the glucose load and number of blood samples.

This explains why two laboratories may quote different prices for what sounds like the same test.

A three-sample test requires an additional blood collection and measurement compared with a two-sample test. A five-sample protocol may require the patient to remain at the facility much longer.

Location: Avire Tower, P. Tuazon Boulevard, Project 4, Quezon City.

Hi-Precision OGTT Price

Hi-Precision offers pregnancy OGTT services at many branches. Hati Health’s accessible listings show these examples:

The 75 g pregnancy OGTT listing includes three blood extractions. The exact amount can differ depending on the selected branch and booking arrangement.

The advertised discount is not necessarily available to patients who walk in and pay directly at the laboratory.

What About Other Government and Private Hospitals?

Other published Philippine price comparisons report the following examples:

These figures are from a secondary Philippine healthcare-price comparison. The older 2022 and 2023 prices should be treated as historical references, not confirmed current rates.

Makati Medical Center’s reported range is also much higher than several laboratory examples. Before comparing it with a basic 75 g OGTT, check how many samples and services the quoted amount covers.

Around the middle of pregnancy, most mothers also book a detailed scan. You can check the CAS ultrasound price in the Philippines to include it in your prenatal budget.

OGTT Price for Pregnant Women

If your obstetrician has requested an OGTT during pregnancy, the first thing to check is whether the prescription says 75 g or 100 g. Many pregnant patients undergo a 75 g, two-hour OGTT with three blood samples.

The samples are usually collected:

1. Before drinking the glucose solution, while fasting.
2. One hour after drinking it.
3. Two hours after drinking it.

Published examples for this type of test include ₱480 at Medi Linx and ₱670 through Hati Health at selected Hi-Precision branches. Pregnancy OGTT is commonly performed between 24 and 28 weeks of gestation, although an obstetrician may request testing earlier for patients with certain risk factors.

Why Is OGTT Important During Pregnancy?

Gestational diabetes means high blood sugar first identified during pregnancy. It may not cause noticeable symptoms, so testing can be important even when the patient feels well. Identifying gestational diabetes helps the healthcare team plan appropriate monitoring and treatment.

The OGTT result should be interpreted by the obstetrician using the diagnostic criteria appropriate to the test protocol.

Is the 75 g OGTT Enough for Pregnancy?

A 75 g OGTT is used in a recognized one-step approach to screening and diagnosing gestational diabetes. However, some clinicians and facilities follow a two-step approach involving a 50 g glucose challenge test followed, when indicated, by a 100 g OGTT.

Both approaches exist, and the correct test depends on the doctor’s chosen clinical protocol. Do not substitute a cheaper two-sample test for a three-sample pregnancy OGTT without your doctor’s approval.

75 g vs. 100 g OGTT vs. 50 g OGCT

These tests have different purposes and sampling schedules.

What Is the Difference Between OGTT and OGCT?

OGTT stands for oral glucose tolerance test. It generally includes a fasting blood sample, a measured glucose drink, and additional blood samples taken at specified intervals.

OGCT stands for oral glucose challenge test. The 50 g OGCT is commonly used as an initial pregnancy screening test in a two-step approach. It generally does not require fasting, although facility-specific instructions should be followed.

An abnormal OGCT result may lead to a longer diagnostic OGTT. The 50 g OGCT is not simply a cheaper substitute for a 75 g OGTT.

What Does “2 Extractions” or “3 Extractions” Mean?

An extraction means one blood sample collected at a scheduled time.

For example:

• 2 extractions: Usually fasting and two hours after the glucose drink.
• 3 extractions: Usually fasting, one hour, and two hours after the drink.
• 4 extractions: May be required for a 100 g three-hour pregnancy protocol.
• 5 extractions: An extended schedule with additional timed measurements.

The exact timing should follow the laboratory order, not assumptions based only on the number of samples.

Can You Get an OGTT Free Through PhilHealth YAKAP?

OGTT is included among the laboratory tests available under PhilHealth’s primary care benefit arrangements, now delivered through the YAKAP program. PhilHealth’s Konsulta benefit table explicitly lists oral glucose tolerance testing among covered diagnostic examinations when needed as part of primary care management.

A February 2026 Philippine Information Agency report also identifies OGTT among the laboratory tests covered by YAKAP. However, this does not mean anyone can walk into any laboratory, request an OGTT, and automatically receive it free.

How to Access OGTT Through YAKAP

1. Register with a participating YAKAP provider. Check that the provider is accredited and can arrange the required laboratory test.
2. Undergo clinical assessment. The primary care doctor determines whether OGTT is medically indicated.
3. Obtain the authorized laboratory request. The test may be performed by the YAKAP provider or an approved partner laboratory.
4. Confirm the payment arrangement before testing. Ask whether the examination is included under your provider’s YAKAP arrangements and whether any separate charges apply.

If you already paid for an OGTT independently at a nonparticipating laboratory, do not assume that YAKAP will reimburse that expense.

If complications arise in a pregnancy, other procedures may be discussed with your doctor. One of them is covered in our guide to the raspa price in the Philippines.

How to Prepare for an OGTT

Preparation matters because eating, drinking certain beverages, or changing activity during the test can affect the result.

1. Confirm Your Fasting Instructions

For a fasting OGTT, laboratories commonly require approximately 8–12 hours of fasting. Hati Health’s pregnancy OGTT instructions specify a preferred fasting period of 8–12 hours. Other laboratories may use slightly different protocols, so follow the instructions provided for your particular test.

Plain water is generally allowed before testing unless your laboratory instructs otherwise. Avoid unnecessarily prolonged fasting.

2. Eat Normally Before the Fasting Period

Do not deliberately restrict carbohydrates or start an unusual diet before the test unless your clinician specifically instructs you to do so. Your doctor may provide dietary preparation instructions depending on the testing protocol.

3. Arrive Early

Because the test requires timed blood collections, many laboratories prefer patients to arrive in the morning. For a two-hour OGTT, allow additional time for registration, the fasting blood sample, and preparation. A three-hour or extended protocol will take longer.

4. Drink the Glucose Solution as Instructed

The laboratory will provide a measured glucose solution. Hati Health’s listed protocol instructs patients to consume the full drink within five minutes. Do not bring or substitute an ordinary soft drink or another sugary beverage.

5. Stay at the Laboratory

You will generally need to remain at the facility until all required blood samples have been collected.

During the waiting period:

• Do not eat.
• Avoid smoking.
• Avoid strenuous activity or unnecessary walking.
• Follow the laboratory’s instructions about water.
• Tell staff if you feel faint, nauseated, or unwell.

6. Tell the Staff if You Vomit

Some people feel nauseated after drinking the concentrated glucose solution. If you vomit, tell the medical technologist immediately. The test may need to be stopped and repeated at another time.

7. Bring Food for After the Test

Once the final blood sample has been collected and staff confirm the test is finished, you can generally eat again. Bringing a snack or meal is particularly useful for patients who have been fasting since the previous evening.

How Long Does an OGTT Take?

The required time depends on the protocol.

These are planning estimates rather than guaranteed appointment durations. An online booking page may display a shorter service duration, but patients should still follow the actual blood collection schedule.

Can You Leave the Laboratory During an OGTT?

Usually, you should remain at the laboratory or in the designated waiting area. Timed samples must be collected accurately, and physical activity can affect blood glucose measurements. Ask the staff before leaving the testing area.

When Will OGTT Results Be Available?

Result turnaround depends on the laboratory. Some facilities may release results on the same day, while others may require collection the following day. Ask the laboratory whether results will be sent electronically or must be collected in person.

Possible Extra Charges for an OGTT

The published test price may not cover every related service.

A routine OGTT usually does not require hospitalization. When comparing laboratories, ask whether the price includes the glucose drink, all timed samples, and the laboratory report.

Can an HMO Cover an OGTT?

An OGTT may be eligible for HMO coverage when it is medically indicated, but this depends on the patient’s plan and provider network.

Before booking, check:

• Whether the laboratory accepts your HMO.
• Whether a doctor’s request is required.
• Whether a letter of authorization (LOA) is needed.
• Whether maternity-related tests are included or excluded.
• Whether there are copayments or annual limits.

A laboratory’s HMO accreditation does not guarantee that every OGTT will be covered under every policy.

Senior Citizen and PWD Discounts

Eligible senior citizens and persons with disabilities may qualify for a 20% discount and applicable VAT exemption on qualifying diagnostic and laboratory services under Philippine law. The applicable discount depends on the patient’s eligibility, billing classification, and the relevant legal rules.

Present the required senior citizen or PWD identification before payment. If a laboratory is already offering a promotional online rate, ask how statutory discounts are applied and whether the promotional price can be combined with other discounts.

Frequently Asked Questions

Magkano ang OGTT para sa buntis?

A 75 g pregnancy OGTT with three blood extractions is listed at ₱480 at Medi Linx Laboratory and ₱670 through Hati Health for selected Hi-Precision branches. Other facilities may charge more or less.

Magkano ang OGTT sa public hospital?

UP–Philippine General Hospital lists ₱315 for a 75 g OGTT at its paying-outpatient rate and ₱230 under its service-rate classification. Other government hospitals have different fee schedules.

Ilang oras ang OGTT?

A standard 75 g OGTT takes about two hours after the glucose drink, plus registration and preparation. A 100 g three-hour OGTT generally requires about three hours of timed sampling.

Is fasting required for OGTT?

Yes, fasting is normally required for diagnostic 75 g and 100 g OGTT protocols. Many laboratories specify 8–12 hours. A 50 g OGCT is different and often does not require fasting.

Can I drink water before OGTT?

Plain water is generally permitted during the fasting period, but follow the instructions of the testing laboratory. During the test itself, ask the staff what is allowed.

Is OGTT painful?

OGTT involves routine blood collection, so you may feel brief discomfort from the needle. The glucose drink can also cause nausea in some patients.

What happens if I vomit during OGTT?

Tell the laboratory staff immediately. Vomiting may invalidate the test and require rescheduling.

Is OGTT the same as fasting blood sugar?

No. A fasting blood sugar test measures glucose after fasting, while an OGTT measures the body’s response to a glucose drink over a specified period.

Is OGTT the same as HbA1c?

No. HbA1c reflects average blood glucose over approximately two to three months. OGTT evaluates the response to a glucose load during the testing period. They are used for different clinical purposes.

Can I book an OGTT without a doctor’s request?

Laboratory policies differ, but a doctor’s request is strongly recommended because the correct glucose load, sampling schedule, and interpretation depend on the clinical purpose. PhilHealth YAKAP coverage also requires appropriate clinical assessment and authorization.

Before Booking Your OGTT: Final Checklist

• Check whether your request says 75 g, 100 g, or 50 g OGCT.
• Confirm whether the test needs 2, 3, 4, or 5 blood extractions.
• Ask for the total price, including the glucose drink and all samples.
• Confirm how many hours you need to fast.
• Ask how long you must remain at the laboratory.
• Check whether your PhilHealth YAKAP provider can arrange the test.
• Ask whether your HMO or statutory discount applies.
• Confirm when results will be released.

The most important step before paying is to match the laboratory’s quoted test to your doctor’s exact request. A cheaper two-sample OGTT is not a substitute for a three-sample pregnancy test when the latter is what your doctor ordered.

Glucose screening comes later in pregnancy, long after the first confirmation test. For readers at the very start of the journey, you can check the pregnancy test price in the Philippines.
