If you’ve been told you have occult blood in urine in Charlotte, NC or Columbia, SC, understanding what it means is the first step toward deciding what to do next.

Does Occult Blood in Urine Cause Symptoms?

Occult blood in the urine is often found during routine testing, and many people don’t notice any symptoms. When symptoms do occur, they can help point to the cause. Signs to watch for include:

  • Infection or irritation: Pain or burning with urination, often linked to the bladder or urethra
  • Bladder conditions or infection: Frequent urination or urgency
  • Kidney issues: Flank or back pain, which may be related to stones or inflammation
  • BPH: Difficulty starting urine flow or a stop-and-start stream

Even when symptoms seem straightforward, testing is still needed to confirm what’s actually causing the blood.

What Tests Are Done for Occult Blood in Urine?

You don’t always need advanced testing right away. In many cases, your doctor starts with simple tests and adds more based on the results

Repeat urinalysis with microscopy

If occult blood is first found on a dipstick test, your doctor will usually repeat the test and examine the urine under a microscope. This confirms whether red blood cells are truly present.

Urine culture

If you have symptoms like burning or urgency, a urine culture may be done to check for bacteria and confirm a urinary tract infection.

Blood tests

Laboratory blood tests can be used to evaluate kidney function and look for signs of underlying kidney disease.

Imaging studies

If the cause is not clear, imaging may be recommended to look at the kidneys and urinary tract. This could include an ultrasound or, in some cases, a CT scan.

Cystoscopy

In certain situations, a cystoscopy may be performed. This lets your doctor look inside the bladder with a small camera.

When to Follow Up for Occult Blood in Urine

Occult blood in urine can sound alarming, but it’s only one piece of the picture. What matters most is confirming the result and finding the cause, if there is one.

In many cases, repeat testing shows no ongoing issue. But when blood is confirmed, your doctor may recommend further evaluation to look at your urinary tract and kidney health. This helps catch problems early, when they’re often easier to treat.

If you’ve had a positive test for occult blood in urine in Charlotte, NC or Columbia, SC, it’s a good idea to schedule a visit. A simple follow-up can give you clear answers and peace of mind.
