What should a laboratory manager check when auditing the cryogenic equipment in an IVF lab they are taking over?
Taking over an existing IVF laboratory’s cryogenic equipment without a structured audit creates clinical and regulatory risk that may not surface until an HFEA inspection or a storage incident. The audit should cover four areas. First, vessel condition: check each dewar and dry shipper for frost formation on the outer wall, which indicates vacuum loss, and confirm the static evaporation rate matches the original specification by monitoring LN2 level drop over 48 hours with the lid closed. Second, documentation: locate the original purchase documentation, warranty status, and any previous service or maintenance records for each vessel. Third, sample inventory integrity: confirm that every vessel has a current, accurate inventory of its contents matched to the clinic’s patient records system. Fourth, safety infrastructure: verify that oxygen depletion monitors are fixed, calibrated, and have current service records, and that the cryogenic PPE in use meets current HSE requirements.
Vessels with no documentation, unknown age, or frost formation on outer surfaces should be treated as suspect and replaced before they become the point of failure in a clinical incident. Cryolab supplies replacement storage dewars, dry shippers, and cryogenic safety equipment to IVF laboratories carrying out equipment renewal programmes. Contact Cryolab for an equipment audit checklist tailored to your facility or ask CryoGPT for immediate guidance on cryogenic equipment assessment.
