What is the normal range for hemoglobin (Hgb) in pregnancy?
11–12.5 g/dL (may drop slightly in 2nd trimester due to hemodilution)
What is the normal range for hematocrit (Hct) in pregnancy?
33–39% (can drop mid-pregnancy due to plasma volume increase).
What is the normal WBC count in pregnancy?
5,000–12,000/mm³ (can rise to 15,000–20,000 in labor/postpartum
What is the normal platelet count in pregnancy?
150,000–400,000/mm³ (slight drop is normal; <100,000 is concerning).
What is the normal fasting blood glucose in pregnancy?
≤ 95 mg/dL
What is the normal 1-hour postprandial blood glucose in pregnancy?
≤ 140 mg/dL.
What is the normal 2-hour postprandial blood glucose in pregnancy?
≤ 120 mg/dL.
What is the normal serum creatinine in pregnancy?
0.4–0.9 mg/dL (lower due to increased GFR).
What is the normal BUN (Blood Urea Nitrogen) in pregnancy?
3–13 mg/dL (lower than non-pregnant values).
What is the normal urine protein level in pregnancy?
None to trace; ≥ +1 may require further evaluation.
What is the normal hemoglobin level postpartum?
Approximately 10–12 g/dL, depending on blood loss.
What is the normal hematocrit level postpartum?
Typically 30–40%; recovers over a few weeks.
What is the normal WBC count immediately postpartum
Up to 25,000/mm³ is normal due to stress/inflammation.
What is the normal platelet count postpartum?
Returns to 150,000-400,000/mm3 within a few days.
What happens to blood glucose levels postpartum?
Return to pre-pregnancy levels within 24-72 hours if no diabetes.
What are common urinalysis findings immediately postpartum?
May show trace protein or blood; should normalize in a few days.
What is the normal RUN and creatinine nostnartum?
Returns to pre-pregnancy levels (BUN: 7-20 mg/dL; Creatinine: 0.6-1.1 m
How long does it take iron stores to normalize postpartum?
6-12 months without supplementation.
