Relationship of high pretreatment folic acid level and failure of methotrexate in ectopic pregnancy: a pilot study.

Objective: To test the hypothesis that high (> or =20.7 ng/mL) pretreatment serum folic acid level increases the failure of single-dose methotrexate for ectopic pregnancy.

Study Design: Twenty patients with ectopic pregnancy and measured pretreatment folic acid levels were divided into 2 groups based on pretreatment serum folic acid level (< or > or =20.
