What is a 12 hours fasting cortisol Test in Prayagraj ?
What is 12 hours fasting cortisol?
This test measures the level of cortisol in your blood after a period without food or drink. Cortisol is a hormone made by the adrenal glands. 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 12 hours fasting cortisol measure?
It helps control metabolism, blood pressure, immune response, and how the body handles stress. Measuring cortisol helps detect adrenal or pituitary gland problems. It is used to diagnose conditions like Cushing's syndrome (too much cortisol) or Addison's disease (too little cortisol). Doctors also use fasting cortisol to monitor treatment, check for abnormal daily patterns, and decide if further tests are needed.
What symptoms suggest 12 hours fasting cortisol may be needed?
12 hours fasting cortisol is generally requested as part of a liver function assessment. Doctors commonly investigate this area when someone 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. Whether 12 hours fasting cortisol specifically is the right test depends on your history and what your doctor is looking for. Sample collection for Prayagraj is available at partner labs, with home collection in many areas including Civil Lines and Kydganj; you can confirm availability for your address at booking.
How is 12 hours fasting cortisol performed?
For 12 hours fasting cortisol, a GetVisit phlebotomist in Civil Lines or Kydganj, Prayagraj applies a soft tourniquet, disinfects the site, and collects a small blood sample into a vacuum tube. The visit takes only a few minutes and you can return to your day straight away.
How accurate is 12 hours fasting cortisol?
For 12 hours fasting cortisol, alcohol within 24 hours and strenuous exercise can temporarily raise liver values, so avoid both before testing. The partner laboratory processes the sample under its own quality-control procedures; where it is NABL-accredited, that accreditation covers the laboratory and its defined scope.
Are there any risks to 12 hours fasting cortisol?
There is little to worry about. The needle prick lasts a moment and any bruising fades quickly. If you bruise easily or take blood thinners, tell the phlebotomist in Civil Lines or Kydganj, Prayagraj so they can apply pressure for longer.
Did you know?
For a routine blood cortisol test you usually don’t need to fast, but samples are often taken early morning (about 8:00 AM).

Why Take a 12 hours fasting cortisol Test in Prayagraj ?
When does a doctor order 12 hours fasting cortisol?
12 hours fasting cortisol is commonly ordered as part of endocrine or adrenal function testing and sometimes during evaluation for Cushing’s or Addison’s syndromes. Doctors may request it when patients have unexplained fatigue, weight change, high blood pressure, mood changes, or muscle weakness.
Who should get 12 hours fasting cortisol done in Prayagraj?
Liver risk here combines seasonal water contamination causing hepatitis A and E with rising NAFLD from obesity and diabetes. Flood-prone areas near the confluence face higher exposure during and after the monsoon. NAFLD affects an estimated 25 to 35% of India's urban adults, the majority unaware. Regular liver testing in Prayagraj's residential areas including Civil Lines and Kydganj 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 12 hours fasting cortisol 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. Abnormal results can come from adrenal or pituitary disease, long-term steroid use, severe illness, or stress. A family history of endocrine disorders may make this test more important.
What do 12 hours fasting cortisol results mean?
Mildly elevated ALT or AST (2-3× normal): fatty liver, obesity, or medication effect, often reversible. Moderately elevated (3-10×): active viral hepatitis or drug toxicity, requires urgent investigation. Severely elevated (>10×): acute liver injury, a medical emergency. High bilirubin: liver processing failure, bile duct obstruction, or haemolysis. Low albumin: significant loss of liver synthetic function, seen in advanced cirrhosis or malnutrition.
How often should 12 hours fasting cortisol 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 your 12 hours fasting cortisol results are ready?
Book a follow-up consultation after reviewing your results. GetVisit stores your reports alongside your previous test history, so your doctor sees your full health trend, not just today's snapshot. This longitudinal context significantly improves the clinical value of each repeat test.
