Processing

Receiving Instructions

Centrifuge sample and aliquot serum to a separate plastic vial. Refrigerate serum.

This test must be ordered with Oligoclonal Banding, CSF/Blood (Sendout) [RCOLIG]. If serum and CSF samples arrive together at the lab, an HC1 task is not needed. Forward both samples to the Sendouts bench. If a blood sample is received without CSF:

  1. Review open HC1 Tasks and/or the patient's record in Sunquest Inquiry to determine if the RCOLIG sample was previously received in lab. If so, receive the XOLIGG order and deliver both samples to Sendouts.
  2. If serum is received without an existing RCOLIG order, create a task in HC1 to hold the processed serum sample (refrigerated) while waiting for the CSF. Do not deliver to Sendouts until both samples are received.
  3. Contact the provider or client as needed if the other sample is not received in a timely manner.

Sendouts:

  • Wait for both CSF (RCOLIG) and serum (XOLIGG) samples before batching the order across the interface.
  • Write the sample type ("CSF" or "serum") on the sample labels.
  • Rubberband the serum and CSF samples together.
  • Batch the RCOLIG order outbound over the interface. Track both CIDs to USENT.
    • The XOLIGG code is for serum collection only, and will not batch separately.

Stability: Refrigerated (preferred): 14 days; Frozen: 14 days; Ambient: 14 days.

Reject Due To: Gross lipemia. Gross hemolysis or gross icterus are acceptable.
