No non-conformity was found after okb reviewed all manufacturing and qc records of strips (lot#: u19100412).Strips were manufactured on 10/04/2019 and will expire in 10/2021.Because the suspected strips were not returned to okb, the retained strips (lot#: u19100412) from okb's warehouse were used to re-test with onetouch meter (code: 49) and control solution (level low: batch# 8ah1a95, exp.By dec., 2020; level high: batch# 8ah3a15, exp.By dec., 2020).Testing results (level low: 46/43; level high: 259/256) met the acceptance criteria (level low: 30~80; level high: 230~340), and desiccants of strip vial are functional.The root cause of the complaint is unable to be verified without the suspected strips and more user's information.Therefore, the matter has to be closed out if no further action or information from the user.
