Modern hospital hematology laboratory. 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 ...
Sex verification in sports (also known as gender verification, or as gender determination or a sex test) occurs because eligibility of athletes to compete is restricted whenever sporting events are limited to a single sex, which is generally the case, as well as when events are limited to mixed-sex teams of defined composition (e.g., most pairs ...
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [ 1] This may be due to either a loss of both salt and water or a decrease in blood volume. [ 2][ 3] Hypovolemia refers to the loss of extracellular fluid and should not be confused with dehydration.
The direct and indirect Coombs tests, also known as antiglobulin test ( AGT ), are blood tests used in immunohematology. The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells. [ 1] Since these antibodies sometimes destroy red blood cells they can cause anemia; this test can help clarify the condition.

Nontreponemal tests are an indirect method in that they detect biomarkers that are released during cellular damage that occurs from the syphilis spirochete. In contrast, treponemal tests look for antibodies that are a direct result of the infection thus, anti ...
Titer. Titer ( American English) or titre ( British English) is a way of expressing concentration. [ 1] Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative. The titer corresponds to the highest dilution factor that still yields a ...
