About Us

Granger Genetics employs the most current technology to deliver accurate and reliable results to clinicians. Granger specializes in asparaginase testing offering two assays for monitoring patients on asparaginase therapy. The L-asparaginase assays are laboratory developed tests (LDT) to determine the enzyme activity of L-asparaginase or presence of anti-asparaginase antibodies in patients who have been treated with Asparlas®, Erwinaze®, Oncaspar® or Rylaze®.

Our Goal: Optimal diagnosis for optimal patient care.
