Survey IFS is designed to assist participants in verifying manufacturing interference specifications and to investigate discrepant results caused by interfering substances such as bilirubin and hemoglobin. Multiple kits may be purchased.
Each shipment of IFS will consist of twelve 10.0-mL liquid serum specimens. The expiration date of this material is December 1st of the program year. Participants will receive their evaluations one week after the results have been received by the CAP.
