[2-stage determination of rhesus classification]

A new two-staged method for identifying the rhesus appurtenance of the blood is proposed. During the first stage anti-D-super (IgM monoclonal anti-D-antibodies) are used, during the second stage rhesus appurtenance is identified in a tube using standard universal reagent for determining rhesus factor RhO(D) or it is done using gelatin test with Anti-D (IgG monoclonal anti-D-antibodies). A negative result at stage 1 and positive at stage 2 is a sign of partial antigen D, most probably of the VIth category. Subjects with partial D are qualified as rhesus-positive donors and rhesus-negative recipients.
