What 0.4 mmol/L tells you
Blood ketones of 0.4 mmol/L show light ketosis, equal to 4.2 mg/dL of BHB in the blood.
Most studies draw the line for nutritional ketosis at 0.5 mmol/L, so 0.4 mmol/L sits just under it.
Expect 0.4 mmol/L at the midpoint of the expected range at about hour 15 of fasting, after a mixed meal and without exercise.
Usually the urine strip at 0.4 mmol/L reads on the trace pad, while a breath meter shows about 2 to 5 ppm, and both results are approximate
Use the reading comparison tool to put 0.4 mmol/L beside a strip reading or a breath reading, or to include glucose in the GKI.
