Our testing solutions are rigorously screened to ensure that you receive clear, accurate results. Each product has been validated to perform within a certain period of time. To provide the longest possible expiration dating for our customers, we looked to see which products were most frequently ordered. The quick turnaround allows us to classify these as Standard items, which are always in stock and available for real time delivery. All other items are Non-standard and are manufactured upon request to allow the longest possible dating. Non-standard items usually move from production to shipping within 3 weeks (sometimes sooner).
