Patient's question:
How can a baby be checked for rickets at the hospital? How much does it cost?Doctor's answer:
Diagnosis and Treatment Precautions for Rickets Recommendations:The serum alkaline phosphatase test is currently the most commonly used indicator for the diagnosis and screening of rickets, offering the advantages of high sensitivity, specificity, simplicity, and speed. It has replaced the traditional "three tests for rickets" (serum calcium, serum phosphorus, and serum alkaline phosphatase) and has become the primary auxiliary examination for the early diagnosis of rickets in children. Although alkaline phosphatase is less sensitive and specific than serum 25-(OH)D3 and 1,25-(OH)2D3, it generally meets clinical diagnostic requirements for rickets. Many hospitals now offer this test (e.g., the Provincial Maternal and Child Health Hospital), and the cost is not expensive, ranging from 30 to 400 yuan.
Test Method: Very simple—blood is drawn from a finger prick, and results are typically available within 30 minutes.
Normal Range: Less than or equal to 200 U/L.
Grading: The higher the alkaline phosphatase level, the more severe the "calcium deficiency."
Grading of Alkaline Phosphatase (U/L) and Prevention/Treatment Methods
- Normal: Less than or equal to 200 U/L – Take one dose of cod liver oil daily for prevention.
- Mild: 200–250 U/L (excluding 250) – Take one dose of cod liver oil daily for treatment.
- Moderate: 250–300 U/L (excluding 300) – Use high-dose vitamin D3 treatment.
- Severe: Greater than or equal to 300 U/L – Use high-dose vitamin D3 treatment.
Treatment for Rickets
If a baby is diagnosed with rickets, how should it be treated?
First, it’s important to understand that the key to treating rickets is supplementing vitamin D, not calcium (though calcium supplementation is also essential and cannot be neglected).
Second, rickets is also classified by severity, and different treatment plans should be adopted based on the level of severity.
Additionally, how should calcium be supplemented?
Although calcium supplements are secondary, they are also indispensable. This is often the most concerns for parents.
When choosing a calcium supplement, it’s necessary to consider multiple factors, including composition, content, absorption rate, form, taste, whether it contains vitamin D, and safety and quality.
Composition: Common calcium forms include calcium gluconate, calcium lactate, calcium phosphate, calcium carbonate, chelated calcium, and L-lactate calcium.
Content: There’s no need for excessive amounts—choose based on the baby’s needs. Calcium content of around 100 mg is most suitable.
Absorption Rate: Calcium with higher solubility naturally has higher absorption rates. Two special forms, chelated calcium and L-lactate calcium, have particularly high absorption rates, exceeding those of ordinary calcium by 30–40%.
Taste: This is also very important. Since calcium needs to be taken daily, if it’s given to the baby like a medicine every day, it can be very painful. Choosing a calcium supplement that the baby enjoys is very practical.
Vitamin D Content: Depending on the needs, calcium with or without vitamin D has its own advantages—specific situations should be considered.
Safety and Quality: The safety, hygiene, and quality of all food and health supplements are increasingly being paid attention to.

How to Choose the Most Suitable Time to Take Calcium
It’s best to take it about 30 minutes after feeding. Avoid taking calcium after consuming plant-based foods, as this can reduce absorption rates.
How to Explain Why Blood Calcium Levels Are Normal, Yet the Doctor Still Says the Baby Is Calcium-Deficient
Blood calcium does not reflect the body’s calcium reserves. Maintaining normal blood calcium levels is a fundamental requirement for life. If blood calcium falls below the normal range, it can lead to serious life-threatening complications such as convulsions. Therefore, the body will mobilize all calcium reserves to maintain normal blood calcium levels, which may involve drawing calcium from bones. Thus, bone calcium reflects the actual calcium status of the body, and alkaline phosphatase can indicate calcium levels.
How to View Calcium and Zinc Supplementation Together
It’s not recommended to supplement them simultaneously, as they can interfere with each other’s absorption. It’s best to take them separately, with at least a 4-hour interval.
