Comparative Neuromuscular Laboratory

Sample Submission Form and Instructions

In light of the declaration of a National Emergency due to the COVID-19 outbreak, the Comparative Neuromuscular Laboratory is taking measures to balance the need to protect the health of laboratory personnel while attempting to continue laboratory operations to the extent possible. During this time, the turnaround time for testing and response time to emails and voicemails may be longer than under normal operations. Additionally, we request the submission of muscle and nerve biopsies be postponed through April 13th. Shipment of serum samples can proceed as normal over this period. We ask for your patience and understanding during this time and should you have questions or concerns, please email our laboratory at

Please note that beginning January 1, 2020, the Comparative Neuromuscular Laboratory will be increasing the price of all tests. As in past years, we have made every effort to avoid rate increases even as the price of laboratory supplies, reagents and labor costs have increased. For 2019, however, we must raise all prices due to additional overhead charges imposed on us by UCSD.

Sample form and instructions effective January 2020

Turnaround time

Generally 5-7 working days from receipt of the sample. Turnaround time varies from 5-21 days depending on the requested test (see sample submissions form) and does not include the time necessary for shipping.

Test Cancelation Policy

Cancellation of a test request must be made within 24 hours of receipt of sample and before specimen testing has started. We regret that a cancellation request received after testing has started or after the test result has been reported cannot be honored.

Adding a Test on the Same Specimen

Provided that an adequate quantity of a specimen is available, additional tests may be requested on a specimen within one month of specimen receipt. Each additional request will be billed to the appropriate party. Any additions to samples submitted via Antech, Idexx, or other reference laboratory must be made by the submitting laboratory.
