Results of GH and IGF-1 measurements in five cats with acromegaly
| Case | GH (μg/l) | IGF-1 (ng/ml) |
|---|---|---|
| 1 | 158 | nd |
| 2 | >18 | 451 (>1000 1 year later) |
| 3 | >17 | 1259 |
| 4 | 9.5 | 1466 |
| 5 | nd | 1987 |
The reference range for GH concentration in cats is 2–5 μg/l with concentrations >6 μg/l consistent with acromegaly. The reference range for IGF-1 concentrations in cats is 200–800 ng/ml with concentrations >1000ng/ml consistent with acromegaly. nd = not done.
