Providing saline reacting anti-D cell typing reagent
Clinical and Laboratory Haematology
|January 1, 1979
Summary
Researchers found a new source for saline anti-D reagents. Blood donors immunized for anti-D immunoglobulin prophylaxis can provide this valuable reagent when bled shortly after restimulation.
Area of Science:
- Immunology
- Blood banking
Background:
- Anti-D specific immunoglobulin G (IgG) has been used since 1969 for RhD prophylaxis in D-negative women.
- The availability of saline-acting anti-D for reagent use has decreased.
- A consistent supply of anti-D reagents is crucial for blood typing and compatibility testing.
Purpose of the Study:
- To investigate a potential new source for saline-acting anti-D reagents.
- To assess the feasibility of obtaining anti-D reagents from blood donors undergoing immunization for RhD prophylaxis.
Main Methods:
- 12 male blood donors were immunized to produce anti-D antibodies.
- Donors were bled up to 14 days after restimulation.
- Collected plasma was processed to isolate saline-acting anti-D for reagent use.
Main Results:
- Saline-acting anti-D suitable for reagent use was successfully obtained from the immunized donors.
- The procedure yielded a viable source of anti-D reagents.
- The study demonstrated the potential of this method in 12 donors.
Conclusions:
- Immunized male blood donors can serve as a source for saline-acting anti-D reagents.
- This method offers a potential solution to the diminishing supply of anti-D reagents.
- Further studies may optimize this approach for consistent reagent production.
