Pregnancy-Related Laboratory Education
Laboratory tests may be used at different stages of pregnancy to support maternal and fetal care.
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
The purpose, timing, and interpretation of prenatal tests depend on the pregnancy and professional care pathway. This page does not recommend or interpret a test for an individual pregnancy.
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.
