73990-4
Laboratory2,3',4',5-Tetrachlorobiphenyl (PCB) [Mass/volume] in Serum or Plasma by Confirmatory method
Definition
Quantitative confirmation analysis of 2,3',4',5-Tetrachlorobiphenyl associated with aroclors 1232, 1242, 1248, and 1254, four types of polychlorinated biphenyl (PCB) mixtures. The submitting lab's confirmation threshold is 0.2 ng/mL with analysis performed by GC/MS. Testing is performed to determine environmental or workplace exposure to PCBs.
