| Case no. | Ethnic origin | Age (months) | Calcium (mmol/l) (2.15–2.6) | Phosphorous (mmol/l) (1.3–2.5) | Alkaline phosphatase (IU/l) (230–700) | Parathyroid hormone (pg/ml) (10–60) | 25(OH)D (ng/ml) (5–30)* | 1,25(OH)D (pg/ml) (20–50) |
|---|---|---|---|---|---|---|---|---|
| The normal ranges for biochemical variables are shown in parentheses. | ||||||||
| Cases 1 and 2 had radiological features of rickets; a radiograph of case 1 is shown in fig 1. | ||||||||
| *Serum 25OHD levels <5 ng/ml are found in severe rickets, whereas levels <12 ng/l are considered to be deficient. | ||||||||
| †Parents of this child has started him on an “over the counter” purchased multivitamin preparation between being seen in the child health clinic and venepuncture, 10 days later. | ||||||||
