The American College of Obstetricians and Gynecologists and American Urogynecologic Society encourages organizations producing future guidelines on the evaluation of microscopic hematuria to set sex-specific recommendation. Currently both ACOG and AUGS, recommend that asymptomatic, low-risk, never-smoking women aged 35-50 years undergo evaluation only if they have more than 25 red blood cells per high-power field.1

Guides from the US Preventative Services Task Force and the Infectious Disease Society of America2,3 also recommend screening for:

  • Pregnant women at 12 to 16 weeks of gestation screening for asymptomatic bacteriuria with urine, culture or at their first prenatal visit if later2
  • Periodically screen older and elderly women3

LabCorp offers a test for Urinalysis.
