Penn State researchers develop digital test to directly measure HIV viral load
A milliliter of blood contains about 15 individual drops. For a person with human immunodeficiency virus (HIV), each drop of blood could contain anywhere from fewer than 20 copies of the virus to more than 500,000 copies.

New at-home, saliva-based COVID test as effective as PCR in preliminary analysis
PCR tests, also called molecular tests or nucleic acid tests, are considered the gold standard in detecting the presence of SARS-CoV-2, the virus that gives rise to COVID-19. However, they can take a few days to process, resulting in unnecessary quarantine for negative individuals or delays for those who require proof of negative testing for travel or other commitments.
