Log your lab values or photograph the report. YUTHI rates them instead of diagnosing — and tells you what you can do yourself.
Three things the app does for you. The sources are listed at the bottom of the page.
From blood count to hormones. Each value has a reference bar and an in-depth explanation.
Reference ranges are spans in which most healthy people fall — not a sharp line between healthy and ill.4
Every value lands in one of three levels: in range, worth watching, or to discuss with your doctor. Some limits depend on sex.
Examples: “in range” means
If a value is just outside, it's “worth watching”. Only clearly outside does it say: discuss with your doctor.
Labs don't all write the same way. If you enter a value in a different unit, the app converts it.
An LDL of 3.4 mmol/l would then be “worth watching” — between 3.0 and 4.1.
Instead of typing every value: photograph the lab report. The coach reads the values and the sampling date and logs them for you.
Every value can be edited or deleted afterwards.
From notable values, the app makes concrete steps — always first what you can change yourself, supplements last.
The app never names a dose. Whether a value needs treatment is up to your doctor.
For your next blood test, the app creates a sheet to take along: which values matter, with target range, your latest values and the date.
The form is created as a PDF on your device. What makes sense is up to your doctor.
Tap a value and the app explains it in plain words:
Instead of just a number, you see where your value sits — and what that means.
Example: LDL cholesterol of 130 mg/dl, converted to 3.4 mmol/l. The limits are the same as in the app.
Take a photo of your lab report or type in the values. The app converts units, for example mg/dl to mmol/l.
What does the value measure, which range counts as good, and what does it mean for a long, healthy life? As guidance, not a diagnosis.
The app already calculates these connections today. A connection is not a cause — but it shows you where to look.
The glucose card in the Nutrition area uses the fasting range from your blood values.
The recommendations from your values always start with hydration.
In the Supplements area you'll find your blood values in their own “My blood values” tile.
For notable values, the app also names what movement can contribute.
A logged cortisol value appears on the cortisol card in the Stress area.
In the Sleep area too, your latest cortisol value appears next to the cortisol curve.
For some values, the app suggests applications — for example more daylight.
If you've logged a period in the last 60 days, the app also recommends a ferritin value.
The DGE recommends 16 mg of iron a day for women before menopause and 11 mg for men. Menstruating women, vegetarians and vegans should pay particular attention to their intake. A blood value such as ferritin shows whether your body has enough.1
In one study, lack of sleep worsened glucose tolerance, and light walking after meals kept blood sugar lower afterwards. Sugar values read better when you also look at sleep and movement.23
If your iron value is low: coffee and especially black tea reduce iron absorption. Vitamin C improves it.1
