How many replicates does SCL run for each Total Intact PTH and CAP assay?
SCL is a unique clinical laboratory in that it runs duplicate determinations on each patient sample (provided there is at least 1 ml of plasma sample available) for both the Total “Intact” PTH and CAP assays. Most other clinical laboratories run only single determinations on samples which make it impossible to see discrepancies revealed by imprecision of replicate determinations. SCL reports the mean of the duplicate PTH determinations. SCL automatically repeats PTH determinations at no charge if the replicates exceed the 10% CV limit.
