Our tests

We test blood + saliva and we measure
results by looking at biomarkers.
At-Home Finger Prick
We use a lancet finger-prick method to collect blood samples on a DBS (dried blood spot) card or microtainer. Our blood tests measure the hormone and vitamin levels that help explain why we feel a certain way.
At-Home Saliva
We use our saliva collection to measure the hormone levels that collect in your salivary glands. We use a single tube or multiple tube collection method throughout the day intended to capture hormone levels during a specific time frame.
Quest Diagnostics
You always have the option to go to a local Quest Diagnostics, with the exception of New York, instead an at-home finger prick collection. Any of the finger-prick tests can be replaced with a Quest Lab blood draw.
