Patient's question:
My child is a bit lacking in vitamin D. The doctor asked me to use his hair for a test to determine if he has rickets. Is this method meaningful for diagnosing rickets?Doctor's answer:
Hello, it's a pleasure to assist you: Some small clinics or pharmacies, to encourage parents to buy medicine, claim that hair or urine calcium tests for children can diagnose rickets. They say that this method is non-invasive and painless. However, this method is absolutely unreliable and has been completely rejected by the medical community. A single urine calcium test result is unreliable, while a 24-hour urine calcium test has some value.
