Urine Routine & Culture in Pregnancy
Screens for UTI, pre-eclampsia protein, and gestational diabetes at every antenatal visit
ಇದು ಏನನ್ನು ಅಳೆಯುತ್ತದೆ?
A urine routine examination (urine R/E or dipstick analysis) tests several parameters simultaneously in a single urine sample: protein (indicates kidney stress or pre-eclampsia), glucose (may indicate gestational diabetes), white blood cells and nitrites (indicate urinary tract infection), red blood cells (haematuria — blood in urine), pH, specific gravity, and ketones. A urine culture (midstream clean-catch sent to microbiology) identifies the specific bacteria causing infection and their antibiotic sensitivity. Both tests together provide comprehensive information about kidney and urinary tract health in pregnancy.
ಇದನ್ನು ಯಾವಾಗ ಸೂಚಿಸಲಾಗುತ್ತದೆ?
A urine dipstick is performed at every antenatal visit — typically monthly in the first and second trimesters and fortnightly or weekly in the third trimester. Urine culture is done at the booking visit and any time urinary symptoms develop (burning, frequency, urgency, flank pain, fever). Even without symptoms, a positive dipstick for leukocytes or nitrites triggers a culture.

Protein in urine (2+ or more) when combined with high blood pressure after 20 weeks of pregnancy is a key diagnostic criterion for pre-eclampsia — a serious pregnancy complication that affects blood flow to the placenta and baby and can cause maternal organ damage if untreated. Protein alone (without hypertension) may indicate underlying kidney disease. Glucose in urine (glycosuria) during pregnancy can be a normal finding because the kidneys' ability to reabsorb glucose decreases — but it should always be followed up with an OGTT to rule out GDM. UTI in pregnancy is particularly dangerous: asymptomatic bacteriuria (bacteria in urine with no symptoms) occurs in 5–10% of pregnancies and must be treated because it can ascend to cause pyelonephritis (kidney infection with fever, rigors, and severe illness) and is associated with preterm labour. Unlike non-pregnant women, asymptomatic bacteriuria in pregnancy always requires antibiotic treatment.

UTI is extremely common in pregnancy in South India — partly due to the hot climate increasing dehydration risk, anatomical factors in pregnancy, and cultural norms around delayed urination. Key prevention advice: drink a minimum of 2.5–3 litres of water daily (monitor urine colour — pale yellow is ideal; dark yellow means dehydrated); avoid holding urine for long periods — empty the bladder regularly; always wipe from front to back; eating a cup of curd (yogurt) daily maintains healthy urogenital flora. Tender coconut water (ilaneer) is an excellent natural hydration option. Government antenatal clinics routinely test urine at every visit — if a dipstick shows infection, request a culture to identify the specific organism before starting antibiotics.

Why is protein in urine taken so seriously in pregnancy?
Because significant proteinuria (2+ or more) combined with high blood pressure after 20 weeks is the hallmark of pre-eclampsia — a condition that can rapidly progress to serious complications including seizures (eclampsia), stroke, liver rupture (HELLP syndrome), and fetal growth restriction. Detecting protein early at routine visits allows timely intervention: closer monitoring, blood pressure medication, and timely delivery if needed. Pre-eclampsia cannot be 'treated' — only managed until delivery.
I had glucose in my urine but my blood sugar test was normal. Why?
During pregnancy, the kidneys have a lower threshold for spilling glucose into urine — meaning glucose appears in the urine at lower blood sugar levels than in non-pregnant individuals. This is called renal glycosuria of pregnancy and is harmless. If your OGTT (glucose tolerance test) is normal, you do not have gestational diabetes even with glycosuria. Your doctor may repeat the OGTT at 28 weeks if glycosuria recurs.
I have no symptoms but my urine culture showed bacteria. Do I really need antibiotics?
Yes, in pregnancy — absolutely. Asymptomatic bacteriuria (bacteria in urine without symptoms) in non-pregnant women is usually left untreated. In pregnancy, the risk of it ascending to cause a kidney infection (pyelonephritis) is significantly increased due to bladder compression and hormonal changes in the urinary tract. Pyelonephritis in pregnancy is associated with preterm labour and maternal sepsis. A full antibiotic course (culture-guided) is always recommended for bacteriuria in pregnancy.
What antibiotics are safe for UTI during pregnancy?
The antibiotic chosen must be effective against the bacteria AND safe for the baby. Commonly used safe options include: amoxicillin-clavulanate, nitrofurantoin (not in the third trimester or near delivery), cephalexin, and cefuroxime. Antibiotics to avoid in pregnancy include fluoroquinolones (ciprofloxacin), trimethoprim in the first trimester, and nitrofurantoin near term. Your doctor will choose based on your urine culture sensitivity results.
How do I collect a clean catch urine sample correctly?
Clean catch is important to avoid contamination that gives false positive results. Steps: wash hands thoroughly; clean the urethral opening with a sterile wipe (front to back); start urinating, allow the first stream to flow into the toilet for 2–3 seconds; then collect the midstream urine into the sterile container (do not touch the inside of the container); close the lid immediately. Deliver to the lab within 1–2 hours, or refrigerate. A poorly collected sample may grow contaminating organisms and lead to unnecessary antibiotic treatment.
