Antiglobulin testing, also known as the Coombs test, is an immunology laboratory procedure used to detect the presence of antibodies against circulating red blood cells (RBCs) in the body, which induce hemolysis.

The most common maternal blood group with neonatal DAT-positive results was blood group O (90.8%), with none in mothers with blood group A ().There was no difference in the 24-h serum bilirubin level in the DAT-positive and DAT-negative groups in regard to different maternal blood groups (p = 0.412) or maternal–neonatal ABO incompatibility (p = 0.329).DAT tests for evidence of a reaction between the mother’s and baby’s blood groups. If your baby’s DAT is positive, there is a risk that he/she could develop anaemia (low number of red blood cells) and/or jaundice (yellow colour to the skin). However, only a small number of DAT positive babies will develop these problems. Babies who are .Test Name Direct Antiglobulin Test Test Code DC Specimen Type.

Background: The direct antiglobulin test (DAT) is the cornerstone of the diagnosis of hemolytic disease of the newborn (HDN). The aim of this study was to review the incidence and causes of positive DAT in cord blood in relation to development of HDN. Also Known As: DAT, Direct Coombs Test, Direct Anti-human Globulin Test. Types of Coombs Test: There are two different types of Coombs tests. Direct Coombs Test: The direct Coombs test (sometimes called the direct antiglobulin test) examines red blood cells to see if they have antibodies attached to them.The DAT detects the presence of antibody or complement (or both) on the surface of red cells. Washed red cells from a patient or donor are tested directly with antihuman globulin (Coombs) reagents. When IgG coats red blood cells showing agglutination immediately, direct .Test Requested What the lab does Purpose Cord blood “Blood Group & DAT” and DAT • Blood Group (ABO & RhD) • Report issued Information only.
