What does FIT mean in MEDICAL
FIT, an abbreviation for Faecal Immunochemical Test, is a non-invasive screening tool used to detect occult (hidden) blood in stool samples. It aids in the early detection of colorectal cancer (CRC) and other gastrointestinal disorders associated with blood loss in the digestive tract.
FIT meaning in Medical in Medical
FIT mostly used in an acronym Medical in Category Medical that means Faecal Immunochemical Test
Shorthand: FIT,
Full Form: Faecal Immunochemical Test

What is FIT?
FIT is an immunological test that detects the presence of haemoglobin, a protein present in red blood cells, in stool samples. It is a simple and convenient test that can be performed at home, using a small sample of stool collected on a test card.
FIT Procedure
- A small stool sample is collected on a special card provided in the test kit.
- The card is then sent to a laboratory for analysis.
- The laboratory tests the stool sample for the presence of haemoglobin using an immunological assay.
- Results are typically available within a few days.
Interpretation of FIT Results
- Positive result: Indicates the presence of haemoglobin in the stool, which may be due to CRC or other gastrointestinal bleeding. Further diagnostic tests, such as colonoscopy, are recommended.
- Negative result: Indicates no detectable haemoglobin in the stool, suggesting a low risk of CRC or other gastrointestinal bleeding. However, negative results do not guarantee the absence of these conditions.
- Equivocal result: An indeterminate result that requires repeat testing or further evaluation.
Benefits of FIT
- Non-invasive and easy to perform
- Detects CRC at an early stage, when treatment is most effective
- Reduces the number of unnecessary colonoscopies
- Cost-effective and widely available
Limitations of FIT
- May miss small or slow-growing CRC lesions
- Not as sensitive as colonoscopy
- Cannot distinguish between different sources of bleeding
Essential Questions and Answers on Faecal Immunochemical Test in "MEDICAL»MEDICAL"
What is a Faecal Immunochemical Test (FIT)?
A FIT is a non-invasive test that detects hidden blood in stool samples. It is used as a screening tool for colorectal cancer and other bowel diseases.
How is a FIT performed?
A FIT kit is used to collect a small stool sample. The sample is then placed on a test card and sent to a laboratory for analysis.
How accurate is a FIT?
FITs are highly sensitive and can detect even small amounts of blood in stool. However, they can sometimes produce false-positive results, meaning that they indicate blood when there is none.
What are the limitations of FITs?
FITs cannot detect all types of colorectal cancer or other bowel diseases. They are also less accurate in people with certain conditions, such as hemorrhoids or inflammatory bowel disease.
What happens if my FIT result is positive?
A positive FIT result does not necessarily mean that you have colorectal cancer. It indicates that further testing is needed to determine the cause of the blood. This may involve a colonoscopy or other diagnostic procedures.
Who should get a FIT?
FITs are recommended for people aged 50 and over who are at average risk of colorectal cancer. People with a family history of the disease or other risk factors may need to start screening earlier.
How often should I get a FIT?
FITs are typically recommended every 1-2 years for people at average risk. The frequency may vary depending on your age, risk factors, and test results.
Final Words: FIT is a valuable screening tool for CRC and other gastrointestinal disorders associated with blood loss. It is a simple, convenient, and potentially life-saving test that can help detect these conditions at an early stage when treatment is most effective.
