Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Testing and Detection During Peripartum Hospitalizations Among a Multicenter Cohort of Pregnant Persons: March 2020-February 2021.

Findings highlight potential disparities in SARS-CoV-2 peripartum testing by demographic and pregnancy characteristics. Testing practice variations should be considered when interpreting studies relying on convenience samples of pregnant persons testing positive for SARS-CoV-2. Efforts to address testing differences between groups could improve equitable testing practices and care for pregnant persons with SARS-CoV-2 infections.
