What does pregnant woman urine occult blood 1+ mean

Occult blood in urine of pregnant women is a plus sign. This situation indicates that the urine of pregnant women contains hemoglobin. There is no hemoglobin in normal urine and it should be negative. If there is occult blood in urine, first consider whether there is a renal disease, such as Glomerulonephritis, nephrotic syndrome, in addition to urological diseases, such as urinary stones, urinary tumors, and urinary infections, these need to be ruled out by urinary color ultrasound examination in the Department of Nephrology. In addition, if pregnant women do not take urine samples in the middle of urine, unqualified urine collection may also lead to a plus sign of urine occult blood, which belongs to false positive and needs to be re-examined.
