Blood Flow
Laboratory Testing
|
Donated blood is tested in the laboratory for the safety of transfusion. Some test results are shared with donors for the benefit of their own health care. |
|
 |
Primary Test An autoanalyzer performs blood grouping (ABO, Rh), checks for unexpected antibodies, and screens for infectious diseases (HBV, HCV, HIV, HTLV-I, syphilis). |
 |
Biochemical and Cell Counting Tests Biochemical tests to assess liver function (ALT and g-GTP) and sugar metabolism (glycoalbumin or GA), as well as hematology tests (red cell and white cell counts) are performed not only for the safety of recipients, but also for donor health screening. |
 |
Confirmatory Tests Blood with any reactive screening test undergoes confirmatory testing with specialized equipment and reagents to confirm whether or not the donation is suitable for transfusion. |
 |
HLA Tests Patients who are refractory to routine platelet transfusion may have antibodies to HLA (Human Leukocyte Antigens). We can test patient blood samples for HLA antibodies, and collect HLA-matched platelets on their behalf. This service depends on donors who participate in our HLA-typing program. |
 |
Investigation of Adverse Transfusion Reactions Patient may experience adverse reactions during or after transfusion, such as hypotension, difficulty with breathing, or infection. These cases are investigated to determine if, or how, blood transfusion was related to the reaction(s). |
