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.

How do I tell if I have a TD-4279 meter?

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.

No app in Canada!?

I was disappointed to learn that the app isn’t available to us here in Canada. The machine is great, but the app was also a selling feature.

Good buy.

Always reliable strips.

They work well

Have had no duds in the test strips. They're in plastic cylinders, instead of individually wrapped, which makes it easy to get to them. Price is the same as everyone else. Delivery is relatively fast.

Always happy

Fast delivery, right product, happy they still offer the strips for the old keto-mojo!
