Here are some glucose reference ranges used for decision making using glucometers. Human glucometer numbers are given first. Numbers in parentheses are for non-US meters.
Numbers in curly braces are estimates for an AlphaTrak.
< 40 mg/dL (2.2 mmol/L) {< 70 mg/dL for an AlphaTrak}
- 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 mmol/L) {< 80 mg/dL for an AlphaTrak}
- If before nadir, steer with food, ie, give modest amounts of medium carb food to keep from going below 50 (2.8).
- At nadir, often indicates dose reduction is earned.
50 - 130 mg/dL (2.8 - 7.2 mmol/L) {80 - 160 mg/dL for an AlphaTrak}
- 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 mmol/L){60s for an AlphaTrak}; if
not on insulin, this can be safe.
= 150 mg/dL (8.3 mmol/L) {> 180 mg/dL for an AlphaTrak}
- the lowest level pre-shot for ProZinc, PZI, or other non-depot insulins.
> 150 mg/dL (8.3 mmol/L) {> 180 mg/dL for an AlphaTrak}
- At nadir, indicates a dose increase may be needed when following a tight regulation protocol.
200 mg/dL (11.1 mmol/L) {230 mg/dL for an AlphaTrak}
- no shot level for beginners; may slowly reduce to 150 mg/dL (8.3 mmol/L) {180 mg/dL} for long-acting insulins (Lantus, Levemir, and ProZinc) as mid-cycle data collection shows it is safe
180 - 280 mg/dL (10 - 15.6 mmol/L) {may be 210 - 310 mg/dL for an AlphaTrak}
- 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 mmol/L) {may be >=310 mf/dL for an AlphaTrak},
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.
