HIV tests: Expiration dates are important because tests can have decreased sensitivity and/or specificity, just as expired medications can be less effective. Expired kits or kits which have been stored improperly can give false positives and false negatives. I hope your "false negative" turns out to be a "true negative". Good luck!
