If WBCCC exceeds 30,000 cells/uL, the specimen should be processed in the accordance with the Retest Procedure for ERROR (Code 2008) or INVALID (Type 2) as detailed in the IFU for the following scenarios: - Cases where INVALID test results are observed and are associated with an elevated WBCC. - Cases of valid results in which an elevated WBCC has been observed. 3.
