Test Parameters & Specifications
Sample Stability
- Hemolyzed or clotted samples
- Incorrect sample volume or container
- Samples received after stability period
- Unlabeled or mislabeled samples
Understanding Your Results
High titre (e.g., >1:64)
Indicates significant antibody levels against B antigen, suggesting risk of hemolytic reactions; further testing and clinical evaluation recommended.
Low titre (e.g., 1:16 to 1:64)
May indicate low-level sensitization; monitor clinically and consider repeat testing.
Negative
No detectable antibodies against B antigen; generally indicates compatibility, but clinical correlation is advised.
Consult a doctor if you experience symptoms like fever, chills, nausea, back pain, or jaundice after a blood transfusion, or if you have a history of blood group incompatibility.
Limitations
- ⚠May not detect all subclasses of IgG antibodies
- ⚠Results can be affected by other blood group antibodies
- ⚠Not a standalone diagnostic test; clinical correlation is necessary
Risks & Considerations
- ●Minor bruising or pain at the puncture site
- ●Rare risk of infection or hematoma
- ●Lightheadedness in some individuals
Interfering Factors
- ●Recent blood transfusion within the past three months
- ●Hemolyzed or lipemic samples
- ●Certain medications like immunosuppressants
- ●Contamination during sample collection
