Phosphoglucomutase Typing of Vaginal Swabs
The phosphoglucomutase (PGM) isoenzymes present in blood are also known to occur in semen. Culliford  and Rees and Rothwell  found no discrepancy between the PGM pattern of blood and the corresponding semen samples. Rees and Rothwell warned of possible interferences from vaginal secretions when typing semen from a vaginal swab. Thus, if the female is heterozygous for PGM the enzyme type of the semen cannot be established.
