Ultrasound can be useful for fetal assessment in Kell-isoimmunized pregnancies. Because severe hydrops may develop within six days, ultrasound should be repeated more frequently than once per week even if the delta OD450 values are low.
超声检查对 Kell 血型免疫妊娠的胎儿评估可能有用。由于严重水肿可能在六天内出现,即使 ΔOD450 值较低,超声检查的重复频率也应高于每周一次。
