Blood in Urine? Tests You Should Not Delay

Seeing blood in urine can be alarming, especially when the urine suddenly appears pink, red, or brown. However, visible blood does not always mean the same thing. For example, it can occur with a urinary infection, kidney stone, prostate problems, or other urinary-tract conditions.

Therefore, it is important not to ignore the finding, particularly when it is new, recurrent, or accompanied by pain or other symptoms. A healthcare professional can determine which tests are appropriate based on your age, symptoms, medical history, and examination.

Which test is done for blood in urine?

The first test is usually a routine urine examination, which can detect red blood cells and provide other information about the urine. Depending on the findings and symptoms, your doctor may also recommend a urine culture, kidney function tests (KFT), ultrasound KUB, or other investigations.

For men, PSA testing may be considered when prostate-related symptoms or other clinical factors make it appropriate. However, PSA is not a universal test for every episode of blood in urine.

So, rather than choosing every test at once, the right approach is to identify the likely cause and investigate it appropriately.

Do not ignore blood in urine

Blood in urine is called hematuria. It can be visible to the eye or detected only during urine testing.

Moreover, the amount of blood does not necessarily indicate how serious the underlying cause is. Even a small amount of visible blood deserves appropriate medical evaluation.

What can cause red or pink urine?

Several conditions can cause blood in urine, including:

• Urinary tract infection (UTI)
• Kidney or urinary stones
• Prostate-related conditions
• Kidney disease
• Injury to the urinary tract
• Certain medications
• Other urinary-tract conditions

Additionally, foods or medications can sometimes change urine colour without causing true hematuria. Therefore, testing is useful when the cause is unclear.

Test 1: Urine routine examination

A urine routine test is often an important starting point.

It can examine the urine for:

• Red blood cells
• White blood cells
• Protein
• Glucose
• Bacteria-related indicators
• Crystals
• Other abnormalities

Consequently, the test can help determine whether further evaluation is needed.

Test 2: Urine culture

If a urinary infection is suspected, your doctor may recommend a urine culture.

Unlike a routine urine examination, a culture is designed to identify microorganisms that may be causing an infection. Furthermore, it can help guide antibiotic selection when an organism is identified.

When might urine culture be useful?

It may be considered when blood in urine occurs alongside:

• Burning while urinating
• Frequent urination
• Urgent need to urinate
• Fever
• Lower abdominal discomfort
• Recurrent urinary infections

However, the decision to perform a culture should depend on the clinical situation.

Test 3: Kidney Function Test (KFT)

A Kidney Function Test (KFT) can help assess kidney health.

Depending on the panel, kidney-related blood testing may include measurements such as creatinine, urea, and electrolytes. eGFR may also be reported from creatinine.

This becomes particularly relevant when blood in urine is accompanied by swelling, changes in urination, high blood pressure, or other signs that may point toward kidney involvement.

Test 4: Ultrasound KUB

An ultrasound KUB examines the kidneys, ureters, and bladder.

It may be useful when a doctor suspects a kidney stone, urinary obstruction, or another structural problem.

For example, if blood in urine occurs with sudden or severe side/back pain, a urinary stone may be considered. In that situation, your doctor may recommend imaging such as an ultrasound or KUB.

What can ultrasound KUB show?

Depending on the condition, ultrasound may help identify:

• Kidney stones
• Kidney or urinary-tract abnormalities
• Urinary obstruction
• Changes in kidney size or structure
• Bladder abnormalities

Nevertheless, not every urinary stone is visible on ultrasound, so additional imaging may sometimes be recommended.

Test 5: PSA for men

For men, prostate-related conditions can sometimes contribute to urinary symptoms and blood in urine.

A PSA (prostate-specific antigen) test may be recommended when clinically appropriate, particularly when there are prostate-related symptoms or other risk factors.

However, PSA does not diagnose the cause of blood in urine by itself. A doctor may consider a medical history, physical examination, urine testing, PSA, and other investigations together.

When is it emergency?

Not every episode requires emergency treatment. Nevertheless, seek urgent medical attention if blood in urine is accompanied by severe or worsening symptoms.

Seek urgent care when you have:

• Heavy bleeding or large blood clots
• Inability to pass urine
• Severe side, back, or abdominal pain
• High fever or chills
• Dizziness, fainting, or marked weakness
• Blood in urine following significant trauma
• Severe pain with vomiting

In particular, inability to urinate or significant bleeding requires prompt medical assessment.

What if the blood disappears?

Even if your urine returns to its normal colour, do not automatically assume that the problem has resolved.

Visible blood can occur intermittently. Therefore, if you noticed unexplained red or pink urine, discuss it with a healthcare professional and follow the recommended testing plan.

Can you get urine testing at home?

For routine urine investigations, home sample collection may be convenient when available.

Prima Diagnostics offers home collection services in eligible locations. Consequently, you can ask about same-day collection availability when booking.

Prima same-day urine and ultrasound

If you need urine testing or an ultrasound quickly, ask Prima Diagnostics about same-day availability for your location.

Importantly, same-day availability can depend on the centre, appointment schedule, test type, and service area. Therefore, confirm the collection and ultrasound slot before travelling or arranging your schedule.

What should you do after the tests?

Your next step depends on the results.

For example:

• Urine routine shows infection-related findings: Your doctor may consider culture or other evaluation.
• Urine findings suggest blood without infection: Further assessment may be recommended.
• KFT is abnormal: Your doctor may evaluate kidney function more closely.
• Ultrasound shows a possible stone: Additional stone-focused evaluation may be required.
• PSA is abnormal: Further prostate evaluation may be recommended.

Thus, the tests should be interpreted together rather than separately.

FAQs about blood in urine

Which test is done first for blood in urine?

A urine routine examination is commonly used as an initial test. Depending on symptoms and findings, urine culture, KFT, ultrasound KUB, or other investigations may follow.

Can a UTI cause blood in urine?

Yes. A urinary tract infection can cause blood in urine, particularly when accompanied by burning, frequent urination, urgency, or other urinary symptoms. A urine examination and, when appropriate, culture can help evaluate infection.

Should men get a PSA test?

Not automatically. PSA may be appropriate when prostate-related symptoms or other clinical factors warrant it. A doctor should determine whether PSA is useful in the individual situation.

Can it cause kidney stones?

Yes. Kidney or urinary stones can cause hematuria, often together with side or back pain. Ultrasound KUB and other investigations may be used depending on the clinical situation.

Can I get a urine test at home in Bangalore?

Home collection may be available in eligible Bangalore locations. Check the current service area and same-day availability with Prima Diagnostics before booking.

How quickly should I get blood in urine checked?

Unexplained visible blood in urine should be medically evaluated rather than ignored, even if it disappears. If there is heavy bleeding, severe pain, fever, clots, or difficulty passing urine, seek urgent medical attention.

Book the right test for blood in urine

If you have noticed blood in urine, the next step is not simply to wait and see whether it disappears. Instead, start with an appropriate evaluation and follow your healthcare professional's recommendations.

A routine urine test may be the starting point. Then, depending on the symptoms, your doctor may recommend a urine culture, KFT, ultrasound KUB, PSA for selected men, or additional investigations.

For convenient testing in Bangalore, you can check Prima Diagnostics for urine testing, home collection, and ultrasound availability.

Conclusion

Seeing blood in urine should not be ignored, even if the urine returns to its normal colour. Fortunately, timely testing can help identify possible causes such as a urinary infection, kidney stone, kidney-related condition, or prostate-related problem. Therefore, a urine routine test is often a useful starting point, while urine culture, KFT, ultrasound KUB, or PSA for selected men may be recommended depending on the symptoms and clinical evaluation.

Moreover, if you are in Bangalore, Prima Diagnostics can provide convenient diagnostic testing and eligible home collection services. However, if blood in urine is accompanied by heavy bleeding, clots, severe pain, fever, dizziness, or difficulty passing urine, seek urgent medical attention.

Ultimately, getting unexplained blood in urine evaluated promptly can help identify the cause and ensure that the appropriate next steps are taken.
