Children’s health is a top priority for every family. Conducting regular tests for children is an effective way to ensure proper growth and early detection of any health issues.
In this article from Advanced Cell Labs in Saudi Arabia, we highlight the most important tests your child may need at various stages of growth, helping you monitor their health accurately.
Why Do Children Need Regular Tests?

Regular tests help to:
- Detect chronic or hereditary diseases early
- Evaluate proper growth and development
- Check the function of organs such as liver, kidneys, and thyroid
- Identify vitamin and mineral deficiencies like iron, calcium, and Vitamin D
- Monitor any unexplained symptoms
When Should Children Start Testing?
It is recommended to begin tests from the newborn stage, especially newborn screenings. Tests should then continue periodically according to a child’s test schedule:
- Comprehensive tests for children at least once a year
- Routine tests when symptoms appear or there is a hereditary predisposition
Complete Blood Count (CBC) for Children
The CBC is one of the first and most important tests for children. It measures red blood cells, white blood cells, and platelets, helping detect:
- Anemia

Thyroid Test for Infants and Children
The thyroid regulates growth and energy. TSH and T4 tests are recommended, especially in early childhood, to detect:
- Hypothyroidism or hyperthyroidism
- Delayed physical or mental development
Blood Glucose Test
This test helps detect:
- Type 1 Diabetes
- Metabolic disorders
- Recommended for children with a family history of diabetes or symptoms like excessive thirst or weight loss

Urine and Stool Tests

Vitamin D is essential for calcium absorption and bone building. Recommended tests include:

If your child experiences rashes, vomiting, or diarrhea after certain foods, tests should be done to:

Pre-Vaccination Tests
Sometimes tests are recommended before vaccinations, including:
