Jeff's Topcare Pharmacy

We perform two COVID tests in the pharmacy. A serology test that uses antibodies, and an Antigen Test. Antigen Test can detect and provide results within 3 days of being infected and is a nose swab test.

A serology test, or blood test, usually only tests for IgG which only shows positive after 7-days of being infected and is only valid for past infections.

The manufacturer we use mainly and most new Serology (Blood tests) now also test for IgM antibodies. What that means is that these tests can detect if you are positive or negative COVID infection AFTER three (3) days of being exposed to COVID.

This information is available on line if you search for COVID IgG and IgM test. If you only search for Serology test then you are only reading about IgG positive results. If you have questions please feel free to call us at 832-861-0081.

Hope this helps you understand the tests.
