Question: is hba1c reliable during pregnancy?
Answer: NICE guidelines recommend that HbA1c levels should be below 48 mmol/mol (6.5%) during the first 12 weeks of pregnancy (also called the first trimester). HbA1c levels below 48 mmol/mol (6.5%) help reduce the risk of miscarriage, birth defects in babies, and stillbirth or death in new-borns.
