Introduction
It is normal for pregnant women to have 0–3 red blood cells in urine tests; more than 3 is considered abnormal. Having red blood cells consistently between 0 and 3 in three consecutive urine tests is also generally considered abnormal. Additionally, if a patient's urine test shows elevated red blood cells, they should drink more water, supplement with nutrients, eat more fruits and vegetables, ensure adequate vitamin intake, and avoid spicy and irritating foods as much as possible.

1. Not severe
Red blood cells should not normally be present in urine. The presence of more than 3 red blood cells per high-power field in a urine test indicates microscopic hematuria. When blood in the urine is visible to the naked eye, turning the urine red, this typically means there is about 1 mL of blood per liter of urine, which indicates gross hematuria. Hematuria commonly results from urinary tract stones, urinary system infections or trauma, urinary system tumors, glomerular diseases, or certain medications.
2. Severe
If a pregnant woman has more than 17 red blood cells in her urine, it suggests a severe inflammatory condition. This is usually caused by urinary tract infections, urinary stones, or the enlarged uterus during pregnancy pressing on the bladder or ureters. In such cases, the patient should promptly undergo prenatal examinations at a hospital.
In addition, if a patient's urine test shows elevated red blood cells, she should drink plenty of water, ensure adequate nutrition, consume more fruits and vegetables, maintain sufficient vitamin intake, avoid spicy and irritating foods as much as possible, practice good external genital hygiene, and frequently change undergarments. To determine the underlying cause, it is best to visit a reputable hospital for evaluation and receive targeted treatment under a doctor’s guidance.
