Background:
Part of liver function test profile/bone profile
Age-specific reference ranges will be stated on each individual report.
ALP concentration is commonly increased during growth, healing fractures, or during pregnancy (placental origin). Unexplained elevation of ALP is suggestive of bone or liver disease. Co-existing elevation of GGT indicates hepatic source of ALP.
Reference ranges:
| Age range | Reference range (U/L) |
|---|---|
| < 30 days | 70 - 380 |
| < 16 years | 60 - 425 |
| > 16 years (adults) | 30 - 130 |

Results outside the reference range do not necessarily indicate disease. Similarly, results within the reference range do not preclude abnormality. Please contact the Duty Biochemist for discussion of individual patient results
