Different samples can tell us different things. Qyn starts with blood because it gives us a direct, clinically familiar view of circulating hormone levels.
Blood is already central to how many hormones are measured and interpreted in clinical care.
The problem isn’t blood itself.
It’s that we typically see it one moment at a time.
Qyn is being built to make blood-based hormone measurement easier to repeat — so individual readings can begin to form a pattern.
Measures hormones circulating in the bloodstream
The established clinical matrix for measuring many hormones and guiding diagnosis and treatment.
Measures hormones present in saliva
Useful for select applications, but concentrations and their relationship to blood vary by hormone and collection conditions. For estradiol, levels sit near the edge of what strips can reliably read.
Measures hormones and metabolites excreted over time
Useful for understanding how the body processes and eliminates certain hormones, but it represents a different biological picture than circulating blood levels. It reports breakdown products hours later — not the level your clinician doses against.
Measures biomarkers released through sweat
Researchers have detected hormones in sweat, and the science is real. But sweat runs far below blood levels, shifts with hydration and sweat rate, and no published method converts a sweat reading into the blood value a clinician can use. For estradiol, that conversion doesn't exist.
Only blood measures the hormone itself, in the units your clinician uses. That’s why Qyn starts there.
Your hormones change over time.
Qyn is being designed for repeat measurement, helping reveal changes that a single reading alone can’t show.
Your levels. Your pattern. Over time.
Qyn uses aptamer-based sensing to recognize specific hormones in a small blood sample. Aptamers are molecules engineered to bind to a specific target. When that binding happens, Qyn reads an optical change and translates it into a measurement.
