Understanding RBC Presence in Urine: A 37-Year-Old's Inquiry
Hello everyone, I'm a 37-year-old male seeking some clarification. Last Friday, I underwent a microbiological urine examination, which indicated the presence of 5-6 red blood cells (RBCs) per a specific measurement unit noted as n/10. Unfortunately, I'm not familiar with the implications of this notation. To add to the uncertainty, I returned three days later for a dipstick urine test at a polyclinic, which surprisingly returned a negative result for RBCs. This discrepancy has left me quite perplexed. I'm reaching out to see if anyone could shed some light on the meaning of these findings and what they might signify. Thank you!

It’s understandable to feel confused about the presence of red blood cells (RBCs) in your urine, particularly given the conflicting test results. Let’s break down what this could mean.
Key Points
- Presence of RBCs in Urine: The finding of 5-6 RBCs per measurement unit in your initial test indicates that there was a small amount of blood in your urine.
- Negative Dipstick Test: The subsequent negative result from the dipstick test suggests that there may not be a significant or active source of bleeding at this time.
Explanation
- RBCs in Urine: Typically, a few red blood cells (0-5 are often considered "normal") can appear in urine due to various reasons like mild dehydration, strenuous exercise, urinary tract infections (UTIs), or even minor kidney issues.
- Test Discrepancy: The difference between the two tests might occur due to variations in sensitivity between the tests. The microbiological test can detect lower levels of RBCs compared to the dipstick test, which may require a higher concentration to show positive.
Next Steps
- Hydration: Ensure you are well-hydrated. Dehydration can lead to concentrated urine and may contribute to the presence of RBCs.
- Monitor Symptoms: Pay attention to any symptoms such as pain during urination, frequent urination, or any visible blood. If you experience any of these symptoms, take note.
- Repeat Testing: Consider repeating a urine test after a few days or when symptomatic to verify the presence of RBCs and to get a clearer picture. It would be helpful to discuss this possibility with your health provider.
- Document Symptoms: Keep a record of any accompanying symptoms, changes in urine color, or frequency, which can aid in evaluation.
If you have persistent concerns or new symptoms develop, consider revisiting your healthcare provider to explore this further. It's important to address any underlying issues, even if they do not seem urgent at the moment.

Semen Analysis Results: Assessing Low Motility and Vitality — Are They Temporary due to Stress?
Hello everyone, I’m a 36-year-old male and I recently received the results of my first semen analysis. I’m seeking to determine if the findings indicate a significant medical issue or if they are possibly linked to situational factors. Here’s some context that could be relevant: - I experienced considerable stress during the week the test was conducted. - My sleep quality was particularly poor the night before the test. - Since the collection took place at a clinic, I felt high levels of anxiety and minimal arousal. - Additionally, the sensation during ejaculation seemed weaker than what I normally experience. Here are the key results from the analysis: - Volume: 2.3 ml - Concentration: 30.9 million/ml - Total sperm count: approximately 71 million - Morphology: 9% (WHO reference is ≥4%) - Progressive motility: 18% (considered low) - Total motility: 36.7% (on the lower side of normal) - Vitality: 39% (low range) - No infections detected, no agglutination, and low white blood cell count The lab remarked on the presence of asthenozoospermia and necrozoospermia, indicating issues with motility and vitality. I also have some pertinent medical background: - I underwent orchidopexy as a child, resulting in one testicle being somewhat smaller while the other appears normal. - A recent urine analysis yielded normal results. - I am experiencing no pain and have shown no indications of infection. Here are my inquiries: - Is it plausible that acute stress, lack of sleep, and anxiety during the clinic visit could lead to significant reductions in motility and vitality in just one analysis? - Considering the normal sperm count and morphology, does this situation imply that the issues might be more functional or temporary rather than permanent? - Should repeating the semen analysis under more favorable conditions be the next logical step?
Is it Safe to Apply a Separated Ointment?
I have a one-month-old daughter who has been dealing with a yeast infection, for which her pediatrician recommended Miconazole cream. After finishing the first tube, I noticed some persistent red spots, prompting the doctor to prescribe another tube. However, I've noticed something concerning with this second tube; it appears to have separated. On squeezing the tube, a white cream and a clear, oily liquid resembling olive oil emerge. Should I attempt to mix the contents of the tube, or is this separation an indication of a problem? I’m unsure whether it is safe to apply this ointment. Unfortunately, my pediatrician’s office is closed for the weekend, and I've already observed that my daughter's rash is beginning to reappear after just half a day without the ointment.
Concerns Regarding My Father's Prostate MRI Results
Greetings, I'm reaching out because my father, who is 71 years old, recently underwent an ultrasound that revealed a nodule. His physician suggested an MRI for further examination, assuring us that there was no immediate cause for alarm. However, the findings indicated a PI-RADS score of 4, with a nodule measuring about 0.5 by 0.6 cm. This nodule, located in the transition zone, is non-encapsulated and poorly defined, though there are no indications of it extending beyond the prostate. His PSA level is 0.96 ng/mL and the PSA density is measured at 0.03, with the prostate’s total volume being 34cc. I find myself anxious over the PI-RADS 4 classification, as it suggests a relatively high risk for cancer, even though the PSA levels appear to be more reassuring. Thankfully, my father is asymptomatic and appears to be in good health. A follow-up appointment has already been arranged, but I’m curious—should I be concerned about any urgent implications or potential serious outcomes from this situation?
Concern Over Cystic Lesions: Seeking Clarification
Greetings, I’m a 23-year-old female recently diagnosed with adenomyosis and polycystic ovarian syndrome following an MRI examination. While I have a scheduled consultation with my doctor in a week, I find myself anxious for clarity on certain findings from the MRI report, which I am sharing below. The report indicates the presence of: - A thicc-walled cystic lesion exhibiting peripheral wall enhancement, approximately 2 by 1.6 cm in size, located in the right ovary, with noted thin internal septation and irregularities in the internal mucosal structure. - A smaller cyst, measuring about 2 cm in diameter, also in the right ovary, displaying thin internal septation. My primary concern regards the thick-walled cystic lesion: could it be benign, or should I be alarmed, indicating a need for further evaluation by my gynecologist? I understand that smaller cysts are generally not a cause for concern, but I wonder if this applies only to those that are uniformly shaped and possess thinner walls. The MRI was performed to evaluate potential endometriosis. A previous transvaginal ultrasound ruled out deep infiltrating endometriosis, prompting the MRI to ensure no abnormalities were overlooked, especially given that my calprotectin level was significantly elevated at over 1000, despite a colonoscopy revealing no signs of inflammation, along with reports of resistance detected externally from the colon suggesting the possibility of endometriosis. While I await my appointment, I would greatly appreciate any insights into these findings. Moreover, the MRI results also highlighted mild pelvic congestion and a small amount of free fluid in the pouch of Douglas (POD). --- Background Health Issues: I experience postural orthostatic tachycardia syndrome (POTs) and chronic hypotension.
Can Blood Test Results Be Inaccurate?
Background: 23, Assigned Female at Birth (AFAB) I undergo testosterone cypionate injections on a weekly basis. As a trans man, I have been receiving testosterone therapy for four years. Recently, I switched to a new hormone specialist and underwent blood testing with him. Historically, my testosterone levels have typically fluctuated between 400 to 600 ng/dL. However, the results from my recent test showed a concerning level of only 67 ng/dL. I have been diligent about my injections, although I did miss one month a few months back due to mental health challenges. Is it possible for testosterone levels to fall so drastically after just a month without a shot? I had the test done six days following my latest injection. I'm left wondering if this level drop is plausible or if it could indicate a mistake in the lab results.
