Agency Okays COVID-19 Blood Spot Self-Collection & Molecular Test Pooling

Pandemic pressures continue to produce unprecedented action from the FDA. The current imperative is to clear assays and collection kits for rapid and easy screening, including products that can be used in home settings. A new barrier was crossed on April 6 when the agency granted Emergency Use Authorization (EUA) for a SARS-CoV-2 antibody detection test used in dried blood spot samples collected at home.

The Symbiotica System

The groundbreaking EUA went to Symbiotica’s COVID-19 Self-Collected Antibody Test System, a prescription-only test designed to detect immunoglobulin G against SARS-CoV-2 in dried blood spots obtained via fingerstick. The kit includes lancets that individuals can use to collect the blood samples themselves and mail to Symbiotica’s California lab for analysis.

“The authorization of the first prescription use, home collection antibody test will play an important role in helping health care professionals identify individuals who have developed an adaptive immune response from a recent or prior COVID-19 infection,” noted Jeff Shuren, director of the FDA’s Center for Devices and Radiological Health, in a statement.

Molecular Test Pooling

Two weeks after clearing the Symbiotica system, the agency amended its guidelines to facilitate authorization for pooling by allowing molecular COVID-19 tests with EUA to be used with pooled samples performed to screen the asymptomatic as part of a “serial testing program,” such as in a school or workplace setting. In other words, specific clearance for the use isn’t required as long as the test developer self-certifies that it has validated the test for pooling and submits its validation data and pooling procedures.
