Rythm’s panel is optimized to use a small amount of blood by leveraging FDA-cleared immunoassay analyzers, which require only microliters of serum per biomarker. The sample you collect at home provides the precise volume needed for the specific set of tests we run.
The amount of blood needed depends on the tests being performed. Rythm’s collection process is designed around a defined panel, so you don’t need to collect extra blood for potential add-on tests. Additionally, despite requiring less blood, Rythm Health ensures accuracy and reliability by using FDA-cleared analyzers in CLIA-certified, CAP-accredited labs. Traditional labs, in contrast, often draw full tubes of blood (5–10 mL each) due to venipuncture tube design and the need to reserve extra volume for potential repeat or add-on tests. Rythm Health’s process avoids this inefficiency by collecting only the volume necessary for the ordered tests.
