Urine Occult Blood Test (Dipstick) Biomarker Testing
It checks for hidden blood in your urine to flag possible urinary tract or kidney issues, with easy ordering and clear follow-up via Vitals Vault/Quest.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
A urine occult blood test checks whether there is blood in your urine that you cannot see. On many lab reports this shows up as “Blood, urine” from a dipstick (chemical strip) test.
A positive result does not automatically mean something serious, but it is a useful signal. It can point toward common issues like a urinary tract infection (UTI), kidney stones, or irritation from exercise, and it can also be the first clue that you need a closer look with urine microscopy.
Because the dipstick can react to red blood cells, free hemoglobin, or myoglobin, the next step is often confirming what is actually present and pairing the result with symptoms and other urinalysis findings.
Do I need a Urine Occult Blood test?
You may want this test if you have urinary symptoms such as burning, urgency, pelvic discomfort, flank (side) pain, or urine that looks pink, red, or cola-colored. Even when your urine looks normal, microscopic bleeding can still happen, and a dipstick is a quick way to screen for it.
This test is also commonly ordered as part of a routine urinalysis during checkups, before certain procedures, or when you are monitoring kidney and urinary tract health. If you have a history of kidney stones, recurrent UTIs, or known kidney disease, it can help catch changes early.
If your result is positive and you are not on your period and you did not have a clear temporary trigger (like a very hard workout), you usually need follow-up rather than guesswork. Testing supports clinician-directed care and helps you and your clinician decide whether you need urine microscopy, a urine culture, repeat testing, or imaging.
This is typically a CLIA laboratory urinalysis dipstick screen; results are not diagnostic on their own and should be interpreted with symptoms and confirmatory testing when needed.

Get this test with Vitals Vault
Vitals Vault makes it straightforward to order urine testing when you want clarity on a symptom or you are following up on a prior abnormal urinalysis. You can order through Vitals Vault and complete your sample collection through a national lab network.
Once your result is back, PocketMD can help you understand what a negative, trace, or positive “blood” finding usually means, what common false positives look like, and which companion urinalysis markers matter most (like protein, nitrite, leukocyte esterase, and microscopy).
If your result suggests a temporary cause, you can use Vitals Vault to plan a sensible retest window. If it suggests you need medical evaluation, you can bring a clean, organized report to your clinician so the next step is targeted rather than repetitive.
- Order labs without a referral and view results in one place
- PocketMD guidance for next steps and retest timing
- Easy pairing with urinalysis components that add context
Key benefits of Urine Occult Blood testing
- Screens for hidden (microscopic) blood in urine when you have urinary symptoms or risk factors.
- Helps distinguish “something is off” early, before blood is visible to the naked eye.
- Guides whether you need confirmatory urine microscopy to look for actual red blood cells.
- Supports evaluation for common causes such as UTI, kidney stones, and urinary tract irritation.
- Adds context to other urinalysis findings (protein, leukocyte esterase, nitrite) to narrow likely causes.
- Helps you monitor whether a prior abnormal result resolves after treatment or time.
- Creates a clear baseline you can share with your clinician if further workup is needed.
What is Urine Occult Blood?
Urine occult blood is a screening measurement from a urine dipstick that detects heme activity. Heme is the iron-containing part of hemoglobin (from red blood cells) and myoglobin (from muscle). Because of that, the dipstick can turn positive for three different situations: intact red blood cells in the urine (hematuria), free hemoglobin (hemoglobinuria), or myoglobin (myoglobinuria).
Most of the time, a positive result is evaluated as possible hematuria until proven otherwise. The usual next step is urine microscopy, which can confirm whether red blood cells are present and sometimes provides clues about where bleeding may be coming from.
A single positive dipstick does not diagnose the cause. Your symptoms, the rest of the urinalysis, and factors like recent exercise, menstruation, or contamination during collection are often the difference between a benign explanation and a result that needs prompt follow-up.
Dipstick vs. microscopy
Dipstick testing is fast and sensitive, but it is not specific for red blood cells. Microscopy looks directly for red blood cells and can also report white blood cells, bacteria, and casts, which can change what your clinician does next.
Why “trace” can still matter
Some labs report negative, trace, small, moderate, or large. Trace can be transient and harmless, but if it repeats—especially without an obvious trigger—it is often treated as a reason to confirm with microscopy and review risk factors.
What do my Urine Occult Blood results mean?
Low / negative urine occult blood
A negative result means the dipstick did not detect heme activity in your urine at the time of collection. This makes significant hematuria less likely, but it does not rule out every urinary problem, especially if symptoms are strong or intermittent. If you have persistent pain, fever, or urinary symptoms, your clinician may still order microscopy or a urine culture.
In-range (expected) result
For most labs, the expected result is “negative.” If your report uses categories, an “in-range” result generally means no detectable blood on dipstick. When you are monitoring a prior positive, returning to negative is often reassuring, especially if symptoms have resolved and other urinalysis markers are normal.
High / positive urine occult blood
A positive result (trace to large) means the dipstick detected heme activity. Common causes include UTI, kidney stones, prostatitis, vigorous exercise, or contamination from menstrual blood. Because the dipstick can also react to hemoglobin or myoglobin, confirmation with urine microscopy is often the key next step, along with checking related urinalysis markers and your symptoms.
Factors that influence urine occult blood
Collection technique matters: a non–clean-catch sample, vaginal bleeding, or contamination can cause a positive result. Recent intense exercise can temporarily increase urinary blood, and dehydration can concentrate urine and make abnormalities easier to detect. Certain oxidizing agents or very alkaline urine can affect dipstick chemistry, and muscle injury can raise myoglobin and trigger a positive “blood” result even when red blood cells are not present on microscopy.

Frequently Asked Questions
What does “occult blood” in urine mean?
It means the urine dipstick detected heme activity, which can come from red blood cells, free hemoglobin, or myoglobin. It is a screening signal, not a diagnosis, and it is often followed by urine microscopy to confirm whether red blood cells are actually present.
Can exercise cause a positive urine occult blood test?
Yes. Strenuous or prolonged exercise can cause temporary hematuria in some people, and the dipstick may read positive. If you think exercise is the trigger, a common approach is to rest and repeat a clean-catch sample after 24–72 hours, or follow your clinician’s guidance.
Can my period cause a positive result?
Yes. Menstrual blood can contaminate the sample and make the dipstick positive. If possible, collect the sample when you are not bleeding, use a clean-catch technique, and tell your clinician or the lab if timing could have affected the result.
Do I need to fast for a urine occult blood test?
No fasting is usually required for urine dipstick testing. Hydration and timing can affect concentration, so follow the collection instructions and avoid over-hydrating right before the sample unless your clinician advises otherwise.
What follow-up tests are common after a positive urine blood dipstick?
Common next steps include urine microscopy (to count red blood cells), a urine culture if infection is suspected, and reviewing other urinalysis markers like protein, nitrite, and leukocyte esterase. Depending on your age, risk factors, and symptoms, your clinician may also consider kidney function blood tests or imaging.
What if the dipstick is positive but microscopy shows no red blood cells?
That pattern can happen if the dipstick is reacting to free hemoglobin or myoglobin, or due to test interference. Your clinician may look for signs of muscle injury, hemolysis, medication effects, or collection issues, and may repeat testing to confirm the pattern.
