3.5.3 Lactate Dehydrogenase (LD) Assay
◼
Blood cells contain significant levels of LD, and therefore all LD assays are sensitive to
hemolysis caused by release of LD from red blood cells. In the following circumstances,
the results are annotated to help interpret LD activity in the presence of small amounts of
hemolysis.
◼
If HEM is greater than 50 and less than or equal to 100 mg/dL, the printed LD value is
followed by an

If HEM is greater than 100 and less than or equal to 150 mg/dL, the LD value is preceded

If HEM is greater than 150, no result will be indicated, and only
3.5.4 Endogenous Substances
The analyzer judges the quality of each sample, and measures spectrophotometrically the
concentrations of endogenous substances for each run. The levels of Hemolysis (

Levels are scored as 0, 1+, 2+, or 3+ depending on levels of each interferent. The following table
shows the relationship between these scores and the approximate concentration of each endogenous
substance in the sample.
