Notification and handling of Cerebrospinal Fluid (CSF) for Creutzfeld-Jakob Disease (CJD) testing.

What's happening?

The student practice team is informing students and faculty instructors in nursing and laboratory programs about the process for Creutzfeld-Jakob Disease testing (CJD). Specific safety procedures are necessary for the collection and laboratory processing of cerebrospinal fluid (CSF) specimens from possible CJD patients. When a clinical assessment warrants that CJD testing is required:

  • Page the medical microbiologist on-call (under Pathology on-call)
  • Order “CSFCJD” test (CSF CJD 14-3-3 protein assay) in MEDITECH.

Do not wait for other CSF test results before ordering “CSFCJD” testing. CSF specimens from a patient with suspected CJD must be handled using special precautions to ensure the safety of our laboratory staff.

Why is this important?

“CSFCJD” testing will include results for:

  • 14-3-3 protein
  • tau protein
  • EP-QuiIC (end-point quaking-induced conversion) assay.

CJD testing is performed at the National Microbiology Laboratory in Winnipeg. Results are generally available in 2 to 3 weeks. Other CSF testing may not be processed or will be delayed until final CSF CJD results are available.

How will this impact students and faculty instructors?

Students and faculty instructors who are completing student placements in Fraser Health must consult with their clinical areas to determine what other procedures should be followed to ensure that patients, clients, and residents continue to receive safe and quality care.
