HEPARIN-INDUCED THROMBOCYTOPENIA – ANTIBODY ASSAY UPDATE

March 19, 2019
Alverno Laboratories is pleased to announce that we will be switching platforms for Heparin Induced Thrombocytopenia (HIT) antibody testing to provide more on-demand testing capability. The HIT antibody assay on the ACL TOP detects anti- Platelet Factor 4-heparin (anti-PF4-H) antibodies, which are the most clinically significant antibodies in patients with HIT. The new assay will be reported qualitatively and the positive or negative result should be used with other information, including clinical context. The assay will continue to be available with and without Serotonin Release Assay (SRA) confirmation testing. It should be noted that a positive HIT result may indicate the presence of heparin-associated antibodies but does not confirm the diagnosis of HIT, as some patients may have naturally occurring antibodies to PF4. Please see ordering information below.
