JKB Antigen Typing - Patient
Also known as: JKB AG
Use
The JKB Antigen Typing - Patient test determines if the Jk(b) (JK2) antigen is expressed on the patient's red blood cells. This test is important for patients to identify their antigen status, especially if the patient is to receive blood transfusions, as it can prevent transfusion reactions due to antigen incompatibility. It provides critical information for determining if the patient is heterozygous or homozygous for the Jk(b) antigen by guiding further testing with JKA Antigen Typing - Patient (2007727).
Special Instructions
For comprehensive analysis, consider ordering the JKA Antigen Typing - Patient test (2007727) as well to establish heterozygosity or homozygosity for the Jk(b) antigen.
Limitations
The accuracy of this test relies on proper sample collection and handling. Inappropriate storage conditions or using separator tubes can affect the accuracy of the results. Only refrigerated whole blood samples collected in lavender or pink (K2EDTA) tubes are acceptable. The test may not be suitable for all patient populations, and clinical correlation is necessary to interpret results meaningfully.
