Test Kit and Frequency of Mailing

Proficiency test kits consist of five samples and are mailed three times per year. Laboratories are responsible for using the proficiency testing schedule to track shipment dates for test events in which they participate. Samples must be kept frozen until ready to use.

Source of Samples

The proficiency test samples are prepared by Wadsworth Center staff.

Sample Validation

Acceptable responses must be authenticated by 80% or more of the referee or participating laboratories.

Notification

The laboratory is required to notify the section within five days of shipment that samples have not arrived or are unacceptable for testing. Proficiency test samples are shipped on dry-ice using Federal Express Priority Overnight Service.

Replacement Samples

The laboratory may request replacement samples under circumstances where in routine laboratory practice the recourse in patient testing is to collect additional specimens, e.g., laboratory accident or instrument failure. Requests for replacement samples must be received within five business days from the shipment date.
