Preparation guide
Children's Laboratory Testing
Age-appropriate preparation can help a child understand what will happen during specimen collection and reduce avoidable distress.
Why is this important?
Understanding the purpose and limits of laboratory information can support a more informed conversation with a qualified healthcare professional.
How laboratory testing relates
Explain the procedure honestly in language suited to the child’s age, follow the exact test instructions, and ask the laboratory about collection needs. Clinical decisions remain with the child’s professional care team.
Before testing
Preparation is test-specific. Follow the instructions given for the exact test and contact the laboratory if fasting, timing, medicines, or specimen collection is unclear. Do not stop medicines unless a qualified professional tells you to.
