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.

Participating laboratories are required to notify the section within five days of shipment if
samples have not arrived or are unacceptable for testing. Proficiency test
samples are shipped on dry-ice using UPS Priority Overnight delivery..

routine laboratory practice the recourse in patient testing would be to collect
additional specimens, e.g., laboratory accident or instrument failure.
Requests for replacement samples must be received within five business days
