FDA-cleared Blood Glucose & Ketone Testing Meter
BKT β-Ketone Test Strip, when used together with the TD-4279 β-Ketone & Blood Glucose Monitoring System, allows your β-Ketone levels to be measured by yourself at home. BKT Blood Ketone Test Strips measures from 0.1 mmol/L ~ 8.0 mmol/L. The β-Ketone readings deliver plasma equivalent results and are displayed in millimoles of ketone per liter of blood (mmol/L).
The β-Ketone test measures Beta-Hydroxybutyrate (β -OHB), the most important of the three β-Ketone bodies in the blood.
Normally, levels of β -OHB are expected to be less than 0.6 mmol/L. β -OHB levels may increase if a person fasts, exercises vigorously or has diabetes and becomes ill. If your β-Ketone result is "Lo", repeat the β-Ketone test with new test strips. If the same message appears again or the result does not reflect how you feel, contact your healthcare professional.
Precision: ≤1mmol/L, SD<0.1mM; 1mmo/L, CV<7.5%
Reaction time: Results in 10 seconds
** COMPATIBLE WITH U-Right, iCARE, SUGARCHEK, and ketomojo TD-4279 METERS.

PMOS (formerly PCOS)
PMOS is driven by insulin as much as hormones, and insulin itself stays hidden. Glucose is the metabolic marker you can actually see. One reading before a meal and one after shows how your body handled it — a direct window into your blood sugar response.
Inflammation
BHB, the ketone this meter measures, calms one of the body's core inflammatory pathways. Watching that number climb is a sign the shift you're working toward is underway.
