What is a NT NB SCAN Test in Kolkata ?
What is NT NB SCAN?
The NT NB scan uses ultrasound to measure nuchal translucency (fluid at the back of the fetal neck) and to check the nasal bone. These markers help estimate the chance of chromosomal conditions such as Down syndrome and other fetal problems. The measurements are important because they are noninvasive early signs of possible genetic or structural issues. It is one of the most commonly ordered blood tests worldwide and plays a key role in both preventive screening and the investigation of liver disease.
What does NT NB SCAN measure?
Doctors combine the scan with blood tests and maternal age to calculate risk. High or absent measurements may lead to more detailed scans or diagnostic tests like CVS or amniocentesis. The scan is usually done in the first trimester to guide next steps in pregnancy care. Results are reported in International Units per litre (U/L). Mild elevations (2–3× normal) typically indicate reversible changes. Values above 10× normal suggest acute injury requiring urgent investigation.
What symptoms suggest NT NB SCAN may be needed?
A doctor may order NT NB SCAN when a patient reports fatigue or persistent low energy, yellowing of the skin or eyes (jaundice), dark amber or tea-coloured urine, pale or clay-coloured stools, upper right abdominal discomfort, nausea, loss of appetite, abdominal swelling, and unexplained weight loss. In Kolkata, residents of New Town and Shyambazar commonly present for this test after noticing these symptoms during a routine or preventive consultation.
How is NT NB SCAN performed?
GetVisit home collection in New Town or Shyambazar, Kolkata: a certified phlebotomist arrives at your address at your chosen slot (available from 6:00 AM), brings all sterile single-use equipment, collects the sample, and dispatches it to the NABL-accredited lab. Your digital report is delivered to your GetVisit profile the same day for most standard tests.
How accurate is NT NB SCAN?
All GetVisit partner labs are NABL-accredited. NABL accreditation requires labs to use internationally calibrated reference standards, pass external quality assessments, and maintain internal quality control at every shift. Reports are accepted by all major hospital networks, specialists, and insurance providers in India.
Are there any risks to NT NB SCAN?
This is a low-risk procedure. The only intervention is the blood draw. Side effects are limited to a brief pinch and an occasional small bruise at the puncture site, which resolves in 24 to 48 hours without treatment. Patients on anticoagulants should hold light pressure for 3 to 5 minutes after the draw.
NT NB SCAN Test Preparation in Kolkata
Fasting and dietary instructions:
No fasting required. Eat and drink normally before the appointment. Stay well hydrated , drink 2 to 3 glasses of water before the draw. Avoid alcohol and vigorous exercise for 12 hours before collection.
Medication guidance:
Continue all regularly prescribed medication unless your doctor has specifically instructed otherwise. Inform lab staff about all prescription drugs, supplements, herbal preparations, and protein powders you are taking.
What to bring:
Bring your doctor's prescription or test requisition, a valid photo ID, and your corporate health insurance card if using cashless OPD. Wear short sleeves or clothing with sleeves that roll up easily.
Timing:
Book the earliest available morning slot. For fasting tests, an overnight fast followed by a morning draw represents the optimal balance between adequate fasting duration and test accuracy.

Why Take a NT NB SCAN Test in Kolkata ?
When does a doctor order NT NB SCAN?
Your doctor orders NT NB SCAN in three clinical scenarios: symptom-driven investigation (jaundice, fatigue, abdominal pain), medication safety monitoring (baseline and periodic checks for drugs metabolised by the liver), and preventive screening in high-risk individuals including those with diabetes, obesity, or viral hepatitis.
Who should get NT NB SCAN done in Kolkata?
West Bengal is reported to have one of India's highest hepatitis B carrier rates, estimated at around 4 to 5% of the population. Combined with a diet heavy in mustard oil, sweets, and fried foods, liver disease risk is significant for working adults across Ballygunge, Alipore, and Lake Gardens. NT NB SCAN is part of first‑trimester screening used with blood tests to estimate chromosomal risk. Doctors order it for routine early pregnancy checks, when maternal blood markers are abnormal, or with increased maternal age. NAFLD affects an estimated 25 to 35% of India's urban adults , the majority unaware. Regular liver testing in Kolkata's residential areas including Ballygunge and Dum Dum enables lifestyle intervention before irreversible scarring occurs. Patients recovering from hepatitis, those in alcohol recovery, and anyone with persistently unexplained fatigue also benefit from regular liver monitoring.
What conditions can NT NB SCAN help diagnose?
Very high ALT and AST (10–50× normal) with normal ALP suggests acute hepatocellular injury , viral hepatitis, drug toxicity, or ischaemia. Predominantly elevated ALP and GGT with modest transaminases suggests bile duct obstruction or primary biliary cholangitis. An AST:ALT ratio above 2 suggests alcoholic hepatitis. Persistently low albumin with elevated bilirubin indicates advanced cirrhosis.
What do NT NB SCAN results mean?
ALT above 56 U/L or AST above 40 U/L signals hepatocyte stress. The pattern matters: ALT greater than AST typically suggests NAFLD or viral hepatitis. An AST:ALT ratio above 2 points to alcoholic hepatitis. High ALP with normal transaminases suggests bile duct disease rather than liver cell damage. Low albumin alongside high bilirubin indicates serious loss of liver function.
How often should NT NB SCAN be repeated?
Adults with no liver risk factors and a previously normal result: annually. Patients with NAFLD or treated hepatitis: every 6 months. Patients on hepatotoxic medication: baseline before starting, then at 1 month, 3 months, and every 6 months during treatment. Patients with active liver disease: at intervals specified by their gastroenterologist.
What happens after NT NB SCAN results are ready?
Your GetVisit digital report is delivered to your phone as soon as results are authorised. Share it directly with your doctor via the app, or book a consultation with a GetVisit-verified specialist on the same platform. Critical values outside a safe range are flagged by the laboratory for urgent clinical review.
