Know your numbers with BKT
Tracking glucose to make insulin patterns visible

PMOS (formerly PCOS)

The part of PMOS you can finally see.

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

Ketones do more than signal fat burning.

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.

Questions

Everything you need to know

Every starter kit includes the BKT TD-4279 meter, a lancing device, lancets, test strips (glucose, ketone, or both depending on your kit), a carrying case, batteries, and a quick-start guide. Everything you need to start testing right out of the box.
Yes. The BKT TD-4279 is FDA-cleared for over-the-counter blood glucose and ketone testing. No prescription required.

Intended Use: This Best Ketone Test Ketone and Glucose Meter is intended for the quantitative measurement of glucose in fresh capillary whole blood from the finger, and for the quantitative measurement of β-Ketone (beta-hydroxybutyrate) in fresh capillary whole blood from the finger. The system is intended for in vitro diagnostic use and for single-patient use as an aid to monitoring the effectiveness of a diabetes control program. The system should not be used for the diagnosis of, or screening for, diabetes, nor for use on neonates.

The BKT TD-4279 exceeds strict FDA accuracy standards: ±15 mg/dL for glucose readings at or below 100 mg/dL, and ±15% for readings above 100 mg/dL. Ketone precision is CV < 7.5% for readings above 1 mmol/L.
With the BKT TD-4279, glucose results appear in 5 seconds and ketone results in 10 seconds. Both require just 1.0 µL of blood — a tiny drop from a quick fingertip prick.
The included lancing device has adjustable depth settings so you can find the most comfortable level for your skin. Most users describe it as a quick, mild pinch that's over in a second.
No, only BKT TD-4279 glucose and ketone test strips.
Yes. BKT meter kits and glucose test strips are FSA/HSA eligible, so you can use your pre-tax health savings to purchase. Ketone test strips may also be eligible depending on your specific plan — check with your FSA/HSA provider for details.
Yes. The BKT TD-4279 connects via Bluetooth to the BKT Health app, available on the Apple App Store and Google Play Store. Use it to log readings and track your progress over time.
The BKT TD-4279 stores up to 1,000 readings with date, time, and testing mode. You can also review day averages across 7 to 90-day windows, broken out by before-meal, after-meal, and general readings.
Yes. All BKT starter kits ship free within the U.S. We also ship to Canada and internationally.
Yes! BKT products are also available on Amazon U.S. for your convenience. You can find our full range of starter kits and test strips there.
