Phytohaemagglutinin (PHA, or phytohemagglutinin) is a lectin found in plants, especially certain legumes. PHA actually consists of two closely related proteins, called leucoagglutinin (PHA-L) and PHA-E. These proteins cause blood cells to clump together. PHA-E cause erythrocytes (red blood cells) to clump.
PWM can contribute to B-cell assay or other lymphocytes for testing. The amplified number of proliferated cells makes it easier to test different lymphocyte functions, biological mechanisms, and response to different stimuli. [2] Pokeweed mitogen is also used in research studies to stimulate different lymphocytes and observe change.
ABO blood group determination: Using anti-A and anti-B antibodies that bind specifically to either the A or to the B blood group surface antigens on RBCs, it is possible to test a small sample of blood and determine the ABO blood type of an individual. It does not identify the Rh(D) antigen (Rh blood type).
The fecal immunochemical test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer. [1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia , unexplained weight loss, and abdominal pain .
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The Jurkat cell line (originally called JM) was established in the mid-1970s from the peripheral blood of a 14-year-old boy with T cell leukemia. [2] [3] Different derivatives of the Jurkat cell line that have been mutated to lack certain genes can now be obtained from cell culture banks.
M2-PK, as measured in feces, is a potential tumor marker for colorectal cancer. When measured in feces with a cutoff value of 4 U/ml, its sensitivity has been estimated to be 85% (with a 95% confidence interval of 65 to 96%) for colon cancer and 56% (confidence interval 41–74%) for rectal cancer. [1] Its specificity is 95%. [2]
