Antibody tests, also called serology tests, check your blood to determine if you’ve had COVID-19 in the past. The test is taken through a finger prick or blood draw.

A positive test for antibodies doesn’t necessarily mean you’re immune to COVID-19.

You should get an antibody test if you:

  • Don’t have COVID-19 symptoms
  • Haven’t been sick in the last two weeks
  • Haven’t tested positive for COVID-19 in the last two weeks

These tests can’t be used to determine whether you are currently infected with COVID-19; if you are currently sick, you should get a diagnostic test instead.

Free antibody testing is available for health care workers, first responders, and city agency employees.

Currently, you can sign up if you are an employee of:

  • Correctional Health Services (CHS)
  • Department of Correction (DOC)
  • Department of Health and Mental Hygiene (DOHMH)
  • Fire Department (FDNY)
  • New York Police Department (NYPD)
  • NYC Health + Hospitals
  • Office of the Chief Medical Examiner (OCME)
  • Regional Enrichment Centers, including Early Childhood Centers (DOE REC Centers)

You will first need to complete an online survey to determine your eligibility. If you are eligible for antibody testing, you will then be able to schedule an appointment or find a walk-in location.
