• Medical history - your GP will discuss your child's medical history, diet, family history and any medication that your child is currently taking.
• Blood tests - if rickets is suspected your GP may do some blood tests to measure levels of calcium, phosphorous and vitamin D.
• X-ray - your child may have standard X-rays of their bones and a special X-ray called a bone densitometry scan (DXA scan), which measures the calcium content of the bones.
