Roche diagnostics’ internal investigations found homocysteine reagent lots 173114 and 173121 can lead to under-recovery of results in quality controls (qc) and patient samples. the root cause of the issue has been identified to be the instability of the enzyme, homocysteine s-methyltransferase (hmtase) in reagent r2. lower recovery of affected reagent lots could lead to false low homocysteine results in the worst case scenario. this could further affect the interpretation of the potential risk of atherosclerosis and lead to a delay in diagnosis of atherosclerosis. however, since homocysteine is used for the estimation of long-term cardiovascular risk (late cardiac events), an adverse event due to this issue is extremely unlikely.

Roche is advising customers to immediately discard affected product. Roche will provide unaffected replacement stock. The under recovery issue should be discussed with the medical director to determine whether a look-back is required for previously affected patient results. This action has been closed-out on 26/05/2017.
