According to the Global Cancer Registry (GLOBOCAN) 2018, colorectal cancer is the fifth most common cancer in terms of morbidity and mortality worldwide. In Vietnam, colorectal cancer is tending to be younger and younger. The fecal occult blood test is one of the methods to help detect colorectal cancer.
1. The concept of fecal occult blood test
A fecal occult blood test (FOBT) can help detect very small amounts of blood in the stool. This test will take a stool sample two or three times, using a test kit. Samples are collected from multiple excretions, so any problems can be detected. These samples will be analyzed in a pathology laboratory, and if blood is found, additional tests may be needed. There are currently two different types of FOBT in Australia: guaiac and immunochemical.The guaiac test requires a change in diet and medication and requires stool samples from three different excretions.
Immunochemical testing is generally more widely accepted, as there is no need to change the patient's medications or diet and only requires sampling from two separate excretions.
While the FOBT is not currently the most accurate diagnostic test for bowel cancer, it is the most well-researched screening test, as well as the most widely accepted and least expensive test available. The FOBT test is also non-invasive compared to colonoscopy and colonoscopy.
Dù FOBT hiện chưa phải là xét nghiệm chẩn đoán ung thư ruột chính xác nhất, nhưng là xét nghiệm kiểm tra được nghiên cứu kỹ nhất
2. In what cases is the fecal occult blood test done?
Your doctor will recommend a fecal occult blood test in the following cases:Colon cancer screening: If you are age 50 or older and have an average risk of colon cancer, your doctor may will recommend a fecal blood test every year to screen for colon cancer. In addition, the person may need screening tests that allow the doctor to examine the sign directly.
Evaluate possible causes of unexplained anemia: Anemia is a condition in which red blood cells are not healthy enough to carry adequate oxygen to tissues. Sometimes a fecal occult blood test is used to determine whether gastrointestinal bleeding, such as a bleeding ulcer - is contributing to the anemia.
