We do the SpermMar IgG test, should we also do the SpermMar IgA test?
Most laboratories only do the SpermMar IgG on a routine basis, in case of a positive IgG they also do an IgA. It does happen however that a patient with a negative IgG is positive of IgA. So, from a clinical point of view you should do both SpermMar IgG and SpermMar IgA, from an economical point of view however you would probably opt for the IgG as a routine test and IgA for positive IgG’s.
