Expert writing Tips
Best practice
When discussing specific health outcomes or risks, specify which trimester's level is being referenced to avoid ambiguity. For example, use "first trimester level" instead of just "trimester level".
Common error
Avoid using the phrase without specifying the substance or factor being measured. For example, instead of saying "trimester levels are important", specify "third-trimester iron levels are important for fetal development".
