Proof of Concept for a Polyethylene Glycol/Gel Hybrid Testing Method.

Abstract:

OBJECTIVE:To test a hybrid polyethylene glycol (PEG)/gel method, specifically to attempt to increase reaction strength of accidentally overdiluted anti-Cob and broadly for proof of concept. METHODS:Methods were divided into 2 basic steps: sensitization and antiglobulin (AHG) testing. Sensitization was performed with PEG tubes, followed by AHG using the gel method. One wash was performed between the 2 steps. We tested 7 plasma antibody specimens. RESULTS:In addition to the first specimen, 6 additional antibodies were selected for detection by the PEG/gel hybrid method. Antibody reactivity was detected in all specimens tested with both methods. The PEG/gel method yielded enhanced reactivity in 3 of 7 antibodies (42.9%) and the equivalent of enhanced reactivity in 4 of 7 antibodies tested (57.1%). CONCLUSION:The reactivity of diluted anti-Cob (specimen 1) was increased; thus, our concept proved to be viable. The hybrid PEG/gel method showed the equivalent of enhanced or enhanced reactivity with all specimens tested and provided a stable medium.
