| description | This panel contains the results for lactate dehydrogenase (LD) and LD isoenzymes in serum or plasma. For reporting LD levels in serum, the recommendation is to use one of the method-specific codes because there is a 3-fold difference in normal range between L>P and P>L methods.The methodless LD term is kept in the panel for labs that may still be using it so they will be able to map to this panel. | ||||||||||||||||||||
