COVID-19 Antibody levels: More may be better

Since the beginning of the COVID-19 pandemic, there’s been a lot of talk about testing. Usually, people are referring to diagnostic testing performed with a nasal swab. However, another type of testing—one that requires a blood test and that you may not know about—has been around nearly the whole time.

That testing is for assessing antibody levels against SARS-CoV-2, the virus that causes COVID-19.

Tracking COVID-19 Variants

Labcorp has been regularly tracking variants of the virus throughout the pandemic. The sensitivity of our PCR test is not impacted by these variants. We have been working with the Centers for Disease Control and Prevention (CDC) to provide sequencing of samples of SARS-CoV-2, the virus that causes COVID-19. Our tests remain effective against variants like Omicron and Delta. This is because they are designed to identify segments of the genetic code that are the least likely to mutate. For more information on variants, see our Viral Variation 101 post or read our Guide to Variants.
