Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
To see any decrease or increase in the levels of globulin fraction it should be done in the serum electrophoresis and be checked for any certain abnormalities. [5] Globulins are usually tested through a blood test to see how much protein is in a patient's blood. The blood proteins that should be seen would be globulins and albumin.
The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's plasma and unbound antibodies from the red blood cells) and then incubated with anti-human globulin ("Coombs reagent").
Serum total protein, also known as total protein, is a clinical chemistry parameter representing the concentration of protein in serum. [1] Serum contains many proteins including serum albumin, a variety of globulins, and many others.
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 ...
P1PK (formerly: P) is a human blood group system (International Society of Blood Transfusion system 003) based upon the A4GALT gene on chromosome 22. The P antigen (later renamed P1) was first described by Karl Landsteiner and Philip Levine in 1927. [1] The P1PK blood group system consists of three glycosphingolipid antigens: P k, P1 and NOR.
As with most blood tests, false-negatives can happen, meaning results could come back negative when a cancer does exist — although Grail reports that negative cancer test results from Galleri ...
Hypogammaglobulinemia is an immune system disorder in which not enough gamma globulins are produced in the blood (thus hypo-+ gamma + globulin + -emia). This results in a lower antibody count, which impairs the immune system, increasing risk of infection.
