No special patient preparation is required for serum collection. However, note that this test is designed for genital specimens; serum may have limited sensitivity for genital chlamydial infections. Patients should refrain from urinating for at least 1 hour prior to collection of urethral or cervical specimens. Female patients should avoid douching, vaginal creams, or spermicidal agents for 24-48 hours before specimen collection.
