Sendouts: Samples may be sent to WPHL or directly to the CDC, depending on instruction from the LMR/Micro Fellow.
To CDC via Washington State Public Health Lab:
- Provider must complete the WPHL Serology Requisition. Add the CAST fax number to the form to ensure proper result routing.
- Send sample with the DLMP courier or Delivery Express courier.
Direct Submission to CDC:
- CDC Test: CDC-10458.
- To prevent sample rejections, review the CDC requisition for completion prior to shipment.
- There must be two matching patient identifiers present on the sample and on the CDC requisition. One identifier must be the name, the other identifier can be the MRN, specimen ID, or date of birth. Note that because Sunquest CID labels do not contain the DOB, then either or the MRN or specimen ID must be included on the requisition or the date of birth added to the specimen label.
- Requisitions that are pre-filled by the provider may require additional information to be added after sample collection. This may include: collection date, sample type, date sent to CDC, specimen ID number, etc. Per CDC requirements, additional information may be written on an electronically completed form as long as it is initialed by lab staff making the correction/addition.
- CAST must be entered as the "intermediate submitter" to ensure that result reports are properly routed to the lab from the WAPHL.
