Here are some glucose reference ranges used for decision making
using a human glucometer. Numbers in parentheses are for non-US meters.
< 40 mg/dL (2.2)
- Treat as if
HYPO if on insulin
- At nadir (lowest point between shots) in a long term diabetic (more than a year), may earn a reduction.
< 50 mg/dL (2.8)
- If before nadir, steer with food, ie, give modest amounts of medium carb food to keep from going below 50.
- At nadir, often indicates dose reduction is earned.
50 - 130 mg/dL (2.8 - 7.2)
- On insulin - great control when following a tight regulation protocol.
- Off insulin - normal numbers. (May even go as low as the upper 30s (1.7); if
not on insulin, this can be safe.
> 150 mg/dL (8.3)
- At nadir, indicates a dose increase may be needed when following a tight regulation protocol.
200 mg/dL (11.1)
- no shot level for beginners; may slowly reduce to 150 mg/dL ( 8.3) for long-acting insulins (Lantus, Levemir, and ProZinc) as data collection shows it is safe
180 - 280 mg/dL (10 - 15.6)
- Any time - The renal threshold (depending on data source and cat's renal function) where glucose spills into the urine.
- Test for ketones, glucose is too high.
>= 280 mg/dL (15.6),
if for most of the cycle between shots
- Uncontrolled diabetes and thus at risk for diabetic ketoacidosis and hepatic lipidosis
- Follow your insulin protocol for dose adjustments
- Test for ketones;
if more than a trace level of ketones, go to vet ASAP.
