MTA employees can now take advantage of an extended antibody testing program.

Officials say free testing is available at 52 Northwell Urgent Care locations across the metro area.

The goal is to get a better estimate of the infection rate and also provide those numbers to the state as part of the reopening process.

Testing is available 8 a.m. to 8 p.m. on weekdays, and 9 a.m. to 5 p.m. on the weekends.
