Know More About the Blood Glucose Fasting Test
The Blood Glucose Fasting Test (FBS) measures the concentration of glucose in your blood plasma after a minimum 8–12 hour fast. It is the primary screening and diagnostic test for diabetes mellitus and prediabetes, and one of the most commonly ordered tests in routine health check-ups across India.
The test captures your basal glucose level — the amount of sugar circulating in your blood when your digestive system is completely at rest. This baseline value reflects how effectively your pancreatic beta cells produce insulin and how responsive your body's cells are to it. Even small elevations in fasting glucose — well below the threshold that causes symptoms — indicate a metabolic shift that, if left unaddressed, progresses to Type 2 diabetes over years.
A fasting plasma glucose of 70–99 mg/dL is considered normal. A reading of 100–125 mg/dL indicates impaired fasting glucose (prediabetes) — a critical intervention window where dietary changes, increased physical activity, and weight reduction can restore normal glucose tolerance without medication. A value of 126 mg/dL or above on two separate occasions meets the WHO diagnostic threshold for diabetes mellitus.
A phlebotomist draws a small venous blood sample from your forearm. The sample is processed using enzymatic methods — glucose oxidase or hexokinase — which provide highly accurate plasma glucose readings. Results are typically available within 4–24 hours depending on the lab's processing schedule.
The FBS is routinely ordered as part of annual wellness check-ups, corporate health screenings, and pre-surgical metabolic baselines. Clinicians also order it when a patient presents with symptoms of hyperglycaemia — excessive thirst, frequent urination, unexplained fatigue, blurry vision or slow-healing wounds — or when there is a strong family history of diabetes, obesity, or hypertension.
Clinicians frequently pair the FBS with the Post Prandial Blood Sugar (PPBS) test on the same morning — the fasting draw first, then a standard meal, then the PPBS draw two hours later. This combination captures both fasting and post-meal glucose in a single visit. HbA1c, which reflects average glucose over the preceding three months, complements the FBS as a long-term measure.
In Faridabad, variable diets, physical labour in the industrial belt along Mathura Road, and limited preventive testing access across the NIT sectors and newer Greater Faridabad areas make the FBS an important baseline check. Book from ₹60 and compare NABL-accredited labs on HealthVas.
Who Should Get a Blood Glucose Fasting Test
- Adults with a Family History of Diabetes – If one or both parents or close siblings have diabetes, your genetic risk is significantly elevated. Annual fasting glucose testing helps detect prediabetes years before it causes symptoms, when lifestyle intervention is most effective.
- Overweight or Obese Individuals – Excess body weight — particularly abdominal fat — is one of the strongest modifiable risk factors for Type 2 diabetes. Regular FBS monitoring is recommended for anyone with a BMI above 25.
- Adults Over 45 Years of Age – Insulin resistance increases with age. Adults over 45 with no other risk factors are advised to test fasting blood glucose at least every three years; more frequently if borderline results are found.
- People Experiencing Symptoms of High Blood Sugar – Increased thirst, frequent urination, unexplained fatigue, blurry vision or slow-healing wounds are classic signs of elevated blood sugar and warrant an immediate fasting blood glucose test.
- Pre-Surgical Patients Requiring a Metabolic Baseline – Most surgical protocols require a fasting blood glucose result before general anaesthesia. Elevated preoperative glucose increases infection and complication risk and must be identified before any procedure.
- Faridabad Industrial Workers with Variable Diet and Physical Labour – Workers in Faridabad's industrial belt often combine physically demanding work with irregular, carbohydrate-heavy diets and limited preventive health awareness — a pattern that can mask early glucose intolerance and makes periodic FBS testing an accessible baseline.
How to Prepare
Fast for 8–12 hours before your blood draw. Plain water is allowed and encouraged — staying hydrated makes the vein easier to locate. Avoid all food, sweetened beverages, fruit juice, coffee and tea during the fasting window. Continue any regularly prescribed medications as directed unless your doctor has specifically advised otherwise before the test.
HealthVas partner labs offer free home sample collection across Delhi-NCR — a trained phlebotomist visits your home or office at a time slot you choose, so there is no travel and no waiting room. Reports are delivered digitally and a branded copy can be shared directly on WhatsApp.
Why Compare Lab Prices on HealthVas?
Multiple NABL-accredited partner labs offer the Blood Glucose Fasting Test on HealthVas, and the price for the exact same test can differ widely from one lab to the next. Faridabad has fewer NABL labs per capita than central NCR cities, and price visibility is limited — residents across the NIT sectors, the industrial belt along Mathura Road, and the newer sectors near Greater Faridabad often pay more than necessary for accredited testing.
NABL accreditation is the baseline standard for diagnostic accuracy in India — it certifies that a lab's equipment, reagents and reporting meet national quality benchmarks. Many partner labs additionally hold NABH, ISO or CAP certification, which add stricter internal quality controls. HealthVas shows you the accreditation alongside the price for each lab so you are comparing like with like, not just chasing the lowest number.
Unlike single-lab booking sites that only ever show you their own rate, HealthVas puts the accredited options side by side on one page. You see the lowest available price, the report turnaround, and whether free home collection is included — then book the lab that fits your budget and timeline.
Blood Glucose Fasting Test — What to Know Before Booking
The Blood Glucose Fasting Test measures a single parameter — plasma glucose in mg/dL — after an 8–12 hour fast. It is the primary diagnostic test for both prediabetes and Type 2 diabetes, and is routinely included in annual health check-ups and pre-surgical clearance panels.
The FBS is most commonly paired with the Post Prandial Blood Sugar (PPBS) test on the same morning: the fasting sample is drawn first, the patient eats a standard meal, and the PPBS draw follows exactly two hours later. This combination captures both fasting and post-meal glucose in a single visit. HbA1c, which reflects average blood glucose over the preceding three months, complements the FBS as a longer-term measure.

Frequently Asked Questions
Common questions for this test.
What does the Blood Glucose Fasting Test measure?
It measures the concentration of glucose in your blood plasma after a minimum 8–12 hour fast, expressed in mg/dL. This fasting value reflects your baseline glucose metabolism and your body's ability to regulate blood sugar without the influence of a recent meal.
What is the normal range for the Blood Glucose Fasting Test?
A fasting plasma glucose of 70–99 mg/dL is normal. A reading of 100–125 mg/dL indicates prediabetes (impaired fasting glucose). A value of 126 mg/dL or above on two separate occasions meets the WHO diagnostic threshold for diabetes mellitus.
Do I need to fast for the Blood Glucose Fasting Test?
Yes — an 8–12 hour fast is required before the blood draw. Plain water is allowed. Continue regular prescribed medications unless your doctor has advised otherwise. Avoid sweetened beverages, coffee, tea and all food during the fasting window.
What is the price of the Blood Glucose Fasting Test?
It starts at ₹60 on HealthVas, with the lowest current rate from Dr khanna Pathcare. Prices vary across NABL-accredited partner labs — the live price for each is shown on the page.
Is home sample collection available for the Blood Glucose Fasting Test?
Yes. HealthVas partner labs offer free home sample collection across Delhi-NCR. A trained phlebotomist visits your home or office at a time slot you choose — no travel, no waiting room.
How long do reports take for the Blood Glucose Fasting Test?
Most partner labs deliver results within 24 hours of sample collection. The exact turnaround time for each lab is shown alongside the price on the HealthVas listing page.
Can a home glucometer replace the lab FBS test?
No. Home glucometers measure capillary blood glucose and can vary by ±15–20% from true venous plasma glucose values. They are useful for self-monitoring but are not valid for diagnosis or medical documentation. A NABL-accredited lab test is required for those purposes.
What should I do if my fasting blood sugar is 100–125 mg/dL?
This range indicates prediabetes. It is not a diabetes diagnosis, but it is a clear signal for lifestyle intervention — reducing refined carbohydrates, increasing physical activity, and managing weight. Consult your doctor for a full metabolic assessment including HbA1c and PPBS.
Is FBS the same as fasting blood sugar or fasting blood glucose?
Yes. FBS (Fasting Blood Sugar), fasting blood glucose (FBG), and fasting plasma glucose (FPG) are all names for the same test — a venous blood draw after an 8–12 hour fast, measuring plasma glucose in mg/dL. The terms are used interchangeably.
Why should I compare Blood Glucose Fasting Test prices across labs?
The same NABL-accredited FBS can be priced very differently across labs in the same city. Comparing on HealthVas ensures you pay the lowest accredited rate without compromising quality — every listed lab is NABL-certified.
Do I need a doctor's prescription to book the Blood Glucose Fasting Test?
No. The FBS is a general screening test that does not require a prescription on HealthVas. You can self-refer and book directly.
Are the labs on HealthVas NABL-accredited?
Yes. Every partner lab listed on HealthVas is NABL-accredited. NABL certification verifies that the lab's equipment, reagents, methods, and quality systems meet national standards for diagnostic accuracy.
