Question

A)An area of erythema after a patch test indicates a positive response to a specific antigen. In contrast, an indirect Coombs test detects the presence of circulating antibodies against RBCs; no agglutination is considered a normal finding. Similarly, an eosinophil count of 2% is within the normal range. Finally, an Rh antigen test with a negative result indicates that the client does not carry the antigen; accordingly, this result is not an indicator of a reaction to a specific antigen.
