The shelf life on tests from this site is18 months, so stock up and save with quantity discounts! If you see tests costing considerably less than pricing on this website be sure to ask what the shelf-life is on the tests being sold at a reduced price. Like any other business, some websites offer promotions on products with reduced shelf life in order to move out inventory that is about to expire. Be sure the tests you purchase are FDA approved. Beware of counterfiet products. Drug screening products that are not FDA approved do not offer the same piece of mind in knowing the quality of the test and results are standardized and reliable.
