  • Reason
    The affected lots’ negative predictive value remains unchanged and is nearly 100%. it is only the positive predictive value that is affected. thus, you may choose to continue to use the affected lots to report negative results and perform alternative confirmatory testing on all positive specimens. however, there are risks associated with this choice. the crag lfa is the most sensitive, commercially-available test for cryptococcal antigen. the risk associated with confirming all positive specimens with a less sensitive test is that true, low titer specimens may be negative using a less sensitive test method. thus, a true, low titer positive specimen may be incorrectly reported as negative. clinical evidence must be used in conjunction with test results. .
