22 December 2024 (Sunday) - Historical Records

Just how believable are historic blood groups? There was a post on the Facebook “Blood Bank Professionals Group” about it today in which many people commented about the blood groups recorded on the history of patients grouped whilst on military service which were later found to be wrong.
Obviously you perform a confirmatory group…
 
What if there’s a historic antibody record? Do we trust that or are we sceptical of that too? With the passage of time it isn’t unusual for blood group antibodies to fall below the level of detection. Given that a patient turns up with a supposed history of (say) anti-S, anti-Jk(a) and anti-Jk(b) do we just crossmatch antigen-negative blood or do we phenotype the patient to see if the supposed antibody is plausible (leaving aside the entire concept of auto-antibodies)
