Alyssa Milano revealed that she has tested positive for COVID-19 antibodies after she previously received three false negatives when she was sick.

Tony Danza and Alyssa Milano will star in a "Who's the Boss?" TV sequel.

Alyssa Milano revealed that she has tested positive for coronavirus antibodies.

The "Charmed" actress, 47, shared her test results on Instagram Wednesday. Milano said her positive antibody results came after she previously received three false negatives, despite experiencing "basically every Covid symptom" in late March. .

Milano said her symptoms prompted her to take two COVID-19 swab tests at the end of March and "both were negative." She also took a "covid antibody test (the finger prick test)" that yielded the same result: "NEGATIVE.".

Despite her negative results, Milano said she suffered from lingering symptoms over the next four months, including "vertigo, stomach abnormalities, irregular periods, heart palpitations, shortness of breath, zero short term memory, and general malaise," which led her to get tested again.

Antibody tests check antibodies in your blood to see if you were previously exposed to the virus, according to the Centers for Disease Control and Prevention. The federal agency says "a positive test result shows you have antibodies that likely resulted from an infection with SARS-CoV-2," the virus that causes COVID-19
