Urinary occult blood issue in health check-ups?
On July 2nd, I experienced vomiting and diarrhea due to gastroenteritis, with nearly 10 episodes leading to mild dehydration.
However, I did not replenish much fluid because of a company health check on July 3rd.
After the health check on July 3rd, I received the report last week, which indicated the presence of urine occult blood (1+), red blood cells at 3.5/HPF (reference value 0–3/HPF), and urine red blood cells at 19/μl (reference value 0–16.5/μl).
The urine protein level was normal.
On the same day I received the report, I went to a urology clinic for a repeat urine test, which showed no abnormalities and no occult blood.
I would like to know if I should pursue further testing.

Hello: If you are still concerned, you can repeat the urine test in a month.
If the results are normal, you can continue to monitor.
However, if there is still hematuria, it is recommended to undergo X-ray and urinary system ultrasound examinations.
I hope this answers your questions.

When it comes to interpreting urine test results, particularly concerning the presence of blood in the urine (hematuria), it is essential to understand the context and the implications of the findings. In your case, you experienced gastrointestinal distress, which can sometimes lead to dehydration and may affect urine concentration and composition.
The initial urine test indicated the presence of blood (1+) and a higher than normal count of red blood cells (3.5/HPF), which can be concerning. However, the subsequent test showed no abnormalities, including no signs of hematuria. This discrepancy raises a few important points to consider.
Firstly, transient hematuria can occur due to various benign reasons, such as dehydration, vigorous exercise, or even minor trauma. Given that you had gastrointestinal issues and were dehydrated, it is possible that your initial test results were influenced by these factors. Dehydration can concentrate urine, potentially leading to false positives for blood in the urine.
Secondly, the fact that your follow-up test showed no abnormalities is reassuring. It suggests that the initial finding may have been an isolated incident rather than an indication of a more serious underlying condition. However, it is crucial to consider the possibility of intermittent hematuria, which can occur in some individuals.
In terms of whether you should seek further evaluation, here are some considerations:
1. Symptoms: If you are experiencing any additional symptoms such as pain during urination, frequent urination, back pain, or any other unusual symptoms, it would be prudent to seek further evaluation. These symptoms could indicate a urinary tract infection (UTI) or other conditions that may require treatment.
2. Frequency of Occurrence: If you notice that blood in your urine recurs, even if it is intermittent, it would be wise to consult a healthcare provider. Persistent or recurrent hematuria warrants further investigation to rule out conditions such as kidney stones, urinary tract infections, or more serious issues like tumors.
3. Follow-Up Testing: If you have any concerns or if your symptoms change, it may be beneficial to have additional urine tests or imaging studies (like an ultrasound or CT scan) to ensure that there are no underlying issues that need to be addressed.
4. Consultation with a Specialist: If you are unsure or if there is any lingering concern about your urinary health, consulting a urologist can provide you with specialized insight. They can perform a more thorough evaluation and determine if any further tests are necessary.
In summary, while your follow-up test results are reassuring, it is essential to remain vigilant about your health. Monitor for any new or recurring symptoms, and do not hesitate to seek further evaluation if you have concerns. Maintaining open communication with your healthcare provider is key to ensuring your health and addressing any potential issues early on.
