MCH Blood Test

What is MCH Blood Test? MCH (Mean Corpuscular Haemoglobin) test is a test performed to calculate the average amount of hemoglobin present in the red blood cells of a blood sample. Hemoglobin is an essential protein found in the blood as it is responsible for the transport of gases and nutrients throughout the body. MCH is different from MCHC even …

MPV Blood Test

What is MPV Blood Test? MPV (Mean Platelet Volume) test is a test performed to determine the average size of platelets present in a blood sample. Platelets are important blood cells that are responsible for blood clotting, a process that controls blood loss after an injury. The mean platelet volume (MPV) is the measurement of the dimension of platelets, calculated …

Anisocytosis

Anisocytosis

Anisocytosis Definition Anisocytosis is a medical condition where the sizes of different erythrocytes/red blood cells are unequal. “Aniso” refers to unequal, and “cytosis” refers to the movement or number of cells. Anisocytosis refers to excessive red blood cell size variation which can be quantitatively determined by interpreting peripheral blood films and automated assessment of red blood cell size distribution. The …

Rapid Plasma Reagin (RPR) Test

Rapid Plasma Reagin (RPR) Test

Rapid Plasma Reagin (RPR) like the Venereal Disease Research Laboratory (VDRL) test is a screening test for syphilis which is a sexually transmitted infection caused by the spirochete bacterium Treponema pallidum. It is a rapid non-treponemal test that looks for non-specific antibodies in the blood of the patient that may indicate a syphilis infection. The test does not look for antibodies against the causative bacterium itself but …

Coomb’s Test- Direct and Indirect Coomb’s Test

Result Interpretation of Coomb's Test

Coomb’s Test- Direct and Indirect Coomb’s Test Coomb’s test is a direct agglutination reaction, more commonly known as antiglobulin test. It was discovered by Coombs, Mourant and Race in 1945 originally for the detection of incomplete anti-Rh antibodies. In the test, incomplete antibodies do not agglutinate erythrocytes. Incomplete antibody antiglobulin coats the surface of erythrocytes but does not cause any …

Venereal Disease Research Laboratory (VDRL) Test

Result Interpretation of VDRL Test

The Venereal Disease Research Laboratory test (VDRL) is a screening test for sexually transmitted infection – syphilis caused by the spirochete bacterium Treponema pallidum.  It is a non-treponemal test, which detects antibodies IgM and IgG antibodies to lipoidal material released from damaged host cells as well as to lipoprotein-like material, and possibly cardiolipin released from the treponemes. These antibodies are traditionally referred to as ‘reagins’. …
