Polychlorinated Biphenyls (PCB) Congeners, Screen and Confirmation

This test measures the level of polychlorinated biphenyls (PCBs) in your blood, which are man-made chemicals that can build up in the body over time. It helps determine if you have been exposed to high amounts of these toxins, which are sometimes found in contaminated food or old industrial equipment. This information helps doctors rule out other causes of liver problems or skin conditions by confirming if chemical exposure is a factor. However, this test cannot pinpoint exactly when the exposure occurred or predict specific future health effects.
