LabCorp Supports COVID-19
Blood Plasma Donation

As part of our continued effort to help providers and patients during this global health crisis, LabCorp is offering a no-charge antibody testing program in response to federal health authorities’ request to increase donations of COVID-19 blood plasma. Plasma with COVID-19 antibodies could be helpful when treating patients with an active COVID-19 infection and is being evaluated as a possible treatment.

Beginning August 11, 2020, LabCorp will perform the high-affinity antibody test at no charge to patients, insurance companies, or the government over the next three months. For patients who are receiving other medically necessary blood tests as part of a medically necessary exam or treatment, this program allows you to add the SARS-CoV-2 Antibodies Test (164068) to the same order and the same blood draw at no charge.

Please note: the no-charge high-affinity antibody testing program will use the Roche Elecsys® Anti-SARS-CoV-2 and does not apply to other COVID-19 antibody tests, such as the IgG test.
