Signal
Before you optimize anything, you need a baseline. Signal is where you measure what is actually happening inside your body, so every decision that follows rests on data.

Frequently asked questions
What does Signal mean at Kove?
Signal is the measurement side of longevity: testing where your biology stands, so the rest of your routine has a baseline instead of a guess. Today that means two kinds of at-home test, glycan-based and epigenetic, both processed by accredited labs.
What is the difference between the GlycanAge and TruDiagnostic tests?
They read different biology. GlycanAge measures glycans on your antibodies, which track chronic inflammation and tend to move within months of a real change, so it suits testing, changing something, and testing again. TruAge reads DNA methylation, which moves slowly and adds organ-level detail plus a pace-of-aging measure, so it suits an annual baseline. The two will not agree, and neither one is the wrong answer.
How do the tests work?
Every kit here is an at-home finger-prick. You collect a few drops of blood, mail the sample back in the materials provided, and read your report in your Kove account. No fasting, no clinic visit, no phlebotomist. Each product page lists its own turnaround.
Which one should I start with?
If you want to see whether a change you are making is working, GlycanAge moves fastest. If you want the widest single snapshot, the TruAge + TruHealth kit covers biological age, 11 organ systems, pace of aging, and a full biomarker panel from one collection.
Why test first?
A baseline gives you a reference point. Many people test, build their routine around what the result shows, then test again months or a year later to see how the number has moved.
