Exploring the Connection Between B12 and C-Reactive Protein

7/14/2025, 4:20:19 PMMale25-34

Participant Details: Female, 36 years old, residing in the UK, with no significant medical history, and a lifestyle that does not include smoking or alcohol consumption. Greetings, I am curious about the potential correlation between elevated levels of vitamin B12 and increased serum C-reactive protein (CRP). Is it common for medical professionals to observe both of these markers being raised simultaneously? I am contemplating whether this warrants a more thorough investigation. Current Levels: - Vitamin B12: 1484 (normal range: 211 - 911) - C-Reactive Protein: 13 (normal average is typically below 3) Appreciate any insights!

Elevated vitamin B12 levels alongside high C-reactive protein (CRP) can sometimes occur, but it’s essential to understand the implications of these findings and next steps.

Key Points:

  1. Elevated vitamin B12 can occur for various reasons, including supplementation or certain medical conditions.
  2. High CRP typically indicates inflammation in the body, which can arise from numerous factors, including infection, autoimmune diseases, or other inflammatory conditions.
  3. It is possible for both markers to be high, but they have different implications.

Explanation:

  • Vitamin B12: Your level of 1484 pg/mL is significantly above the normal range. High levels can occur from taking supplements or injections. In some cases, underlying health conditions (like liver disease or certain blood disorders) can also cause elevated B12.
  • C-Reactive Protein: A CRP level of 13 mg/L indicates a significant inflammatory response in your body. This is not normal and would usually prompt further investigation to find the underlying cause.

Next Steps:

  1. Assess Supplement Use: Consider whether you are taking any B12 supplements. If yes, you might want to adjust your intake, especially if it’s high.
  2. Monitor Symptoms: Take note of any symptoms you might be experiencing, such as fatigue, joint pain, or unexplained fever, which could guide further investigation.
  3. Dietary Review: If you consume foods high in B12 (like meat, fish, dairy), this might contribute to elevated levels. Ensure your diet aligns with your needs.
  4. Follow Up on CRP: High CRP levels warrant further investigation to determine the source of inflammation. It could be beneficial to discuss this with a healthcare professional to explore potential underlying causes, including other laboratory tests or imaging if necessary.

If there are any other concerns or symptoms, please keep a thorough log. This can be helpful when discussing with a healthcare provider for tailored advice. Remember, staying proactive about your health is key!

Inquiry About Recent Blood Test Results

Hello, I’m an 18-year-old assigned female at birth (FtM). Currently, I undergo quarterly blood tests as part of my transition, particularly since I’ve been using Testosterone gel (testogel) this past year. In my last full blood count, the results indicated some abnormalities, revealing elevated levels in hematocrit, red blood cells, and hemoglobin. Following this, my general practitioner advised me to schedule a follow-up blood test one month later. I recently received the latest results. While my hematocrit levels appear to be within the normal range now, my red blood cell count and hemoglobin remain elevated with little to no change. Additionally, my mean cell volume has dropped to a low level. A year ago, I was diagnosed with anemia and have been following my GP's recommendation to take iron supplements since then. I plan to consult with my doctor about these results, but I often find that I don’t receive clear information from them. Therefore, I thought I would reach out here as well. Could these changes be related to my use of testogel or could they indicate a different issue?

Concern About Brown Urine

Hello everyone, I’m a 21-year-old woman and I’m uncertain about an issue I’ve been experiencing lately. For the past month, my urine has appeared brown, which initially only happened sporadically. However, last Friday, I noticed it became notably darker, and since then, my urine hasn't returned to its usual yellow color. This discoloration occurs at all times of the day, not exclusively in the morning. While it does lighten a bit after I increase my water intake, it still remains brown. I plan to include some images to illustrate this, although I won’t be including them here. I underwent a urine analysis on Wednesday during a period when it was not too severe, and my urine appeared normal (yellow) then. I am unsure about the accuracy of the findings, but here are the details: - **Protein:** 10 mg/dL - This was previously always negative, now it's detectable but still below the lab’s reference range (≤20). - **Urobilinogen:** 0.2 mg/dL - Previously always negative; although this number doesn’t seem particularly high, the lab typically reports it as negative. - **Epithelial Cells:** Rare (<5/µL) - Below the reference range. - **Leukocytes (urinary sediment):** Rare (<10/µL) - Also below the reference limit. I appreciate any guidance or insights you may have on this issue. Thank you!

Inquiry About Pediatric Billing Practices

I'm seeking clarification concerning a recent pediatric billing issue related to my child, a 16-month-old boy: During a visit for flu symptoms, we took our son to the physician. Our visit wasn't intended for an ear procedure; however, the doctor indicated that some earwax would need to be extracted for her to properly examine one ear. She swiftly removed a small amount of what appeared to be soft wax using a curette. This was the only intervention made involving his ear. Afterward, we received the bill which included the CPT code 69200, described as "Removal of a foreign body from the ear." When I inquired about this billing code, expressing my confusion as there was no foreign object present, the billing department simply stated, "this is the code used for earwax removal by the doctor." I’m wondering whether this application of the code is justified. Should I consider appealing this charge through my insurance? I ended up paying $127.29 post-insurance, and it feels inappropriate that this particular code was utilized since there was no foreign body involved. The procedure appeared simple enough that I could have done it myself, and I don’t recall the use of an otoscope during the process. I would appreciate a more detailed explanation than the response I received if anyone is familiar with these practices. Thank you for your assistance!

Unexpected Loss of Voice During a Cold – Will It Return? M22

Hello everyone, I’m reaching out to see if anyone here has experienced a similar situation and how long it took for your voice to return. I've dealt with colds and flu in the past, but this is the first occasion where I've completely lost my voice. Here’s what transpired: On Day 1, I started with a scratchy throat, extreme fatigue, and a dry cough, which felt like the onset of a typical cold. On Day 2, thankfully, the soreness in my throat and tiredness began to diminish, but the cough lingered. Then, quite unexpectedly while driving, my voice became oddly raspy and hoarse. On Days 3 and 4, I continued to struggle with a rough, weak voice alongside the persistent cough. I’m hoping to hear from those who have gone through similar experiences: Did your voice eventually recover? If so, how long did it take? Is it common for this type of voice loss to happen so abruptly?

Injury to My Big Toe

Recently, I accidentally dropped a weighty piece of metal on my big toe. A month has passed since the incident, and the toe remains discolored and swollen. Thankfully, there’s no pain, and I’m able to move it without difficulty, which leads me to believe there are no fractures involved. Should I simply wait for my toenails to grow out to deal with the blood? Am I at risk for any complications? I've been assuming that as it's my own blood, there’s minimal chance of infection; given the time that's elapsed, any potential complications would likely have already surfaced. 37M
