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.
â¯ Alleles: DNA sequences within a marker or locus (gene and allele sometimes have same meaning). 12 â¢ Now, there are mainly two kinds of makers used today. (1) SNPs (Single nucleotide polymorphism): 1 bp in length; there are two alleles in human population. The two alleles may be any two from {A,G,C,T}.
