International Quality Control

Ensuring Quality Control

The NTSAD International Tay-Sachs Carrier Testing Quality Control Program is a voluntary laboratory proficiency testing program. The program evaluates laboratory performance of Tay-Sachs enzyme testing in serum and leukocytes.  Serum testing is the standard method.  However, leukocyte testing is recommended when the person to be screened is pregnant, on birth control pills or is taking any medications which affect hormones; all which may interfere with the accuracy of the serum test.

The program, which was founded and administered by Dr. Mike Kaback at the University of California-San Diego for 25 years, is now being run in the lab of Dr. Mimi Blitzer and Dr. Erin Strovel at the University of Maryland.
