Managing reagent expiry: from alert to disposal

Expired reagents are wasted money and a quality risk. Managing expiry as a process, with time to act, turns most expiries into used stock instead of waste.

Alert early enough to act

An alert on the day of expiry is a record of failure. Aim for warnings weeks ahead, so stock can be used first, moved to a busier branch or returned to the supplier where terms allow.

Separate near-expiry from expired

Near-expiry stock is still usable and should be prioritised. Expired stock must be removed from use immediately and visibly. A single list that mixes the two invites mistakes.

Record disposal properly

Disposal is a controlled event: what was disposed, how much, why and by whom. Recording it keeps stock counts correct, supports waste reporting and gives an auditor the end of the story.

Learn from the pattern

If the same item expires repeatedly, the problem is the order quantity, not the expiry. Review expired value by item each month and adjust reorder levels.

Common questions

Only under your laboratory's documented policy and the manufacturer's guidance, with appropriate verification. Most quality systems prohibit it.

Many laboratories choose a window long enough to use the stock at current consumption, plus time to transfer or return it. Slow-moving items need a longer window.
