The reason for the recall is one of the test pads, for the parameter leukocytes, was missing on some of the test strips. The issue was identified by a consumer by way of a Henry Schein Inc. (HSI) customer complaint. This problem can potentially result in the possibility that the parameter leucocytes (a non-specific marker for urinary track infections and an indicator for inflammatory renal processes) is interpreted instrumentally as a false negative . The following HSI item number and lot number were affected: Urispec¿ 11-Way, #102-2285, LOT 65402.
