Two blood tests can check for antibodies that attack red blood cells: the direct Coombs test and the indirect Coombs test. The direct Coombs test is done on a sample of red blood cells from the body. It detects antibodies that are already attached to red blood cells.
1 Marker: A specific place on a chromosome with two or more forms, called alleles, the inheritance of which can be followed from one generation to the next. 2  In Y-chromosome DNA testing, this refers to non-coding Y-chromosome DNA.3  Numbers designate the individual DNA segments. For example, in humans, one allele of the eye-color gene produces blue eyes and another allele of the eye-color gene produces brown eyes. 2  Administrator: Also known as a Project Administrator, Group Project Administrator, Project Manager, Coordinator and Co-Coordinator.
Markers can be an expressed region of DNA (gene encoding a protein) or a segment of DNA with no known coding function but whose pattern of inheritance can be determined. A marker can be localised to a specific region of the genome (e.g., all markers on the human transcript map are STSs). Markers have also been defined as a genetic trait, of which one allelic form is selected or screened for after recombination. Suicidology A potential physiologic indicator or predictor of an increased risk of suicide, the most promising of which is a decrease in serotonin in the brain. marker
