Prior to collection, most self collection kits are usable up to 1 year from time of purchase.
Once you have collected your sample, the lab must process it within 30 days of collection. This is meant to ensure the stability and integrity of the sample. If a sample exceeds the 30-day limit after collection, or if it is deemed compromised by other means, the lab will reject the sample. To be safe, we recommend returning your kit as soon as possible after collecting your sample.
