Confusion About Blood Type: Is It Possible It Changed?
Hello! I recently came across a box of my childhood belongings that my mother sent me, and among them was a card from the Neonatal Intensive Care Unit (NICU) showing my details. Notably, it listed my blood type as "O+" in the RH section. Additionally, I found a photograph of myself in an incubator, where a prominent sign also indicated "O+". However, after the birth of my own child, I underwent blood testing at a diagnostic lab, which resulted in my blood type being identified as "A+". To my knowledge, I have never received a blood transfusion or undergone a stem cell transplant. Could my blood type have changed to "A+" at some point, or is there a possibility that an error occurred in the 1980s, and I have actually been "A+" all along? I'm just trying to understand what might have happened. Thank you for any insights you can provide!

It sounds like you have some valid concerns and questions regarding your blood type history. To clarify, your blood type typically does not change throughout your life under normal circumstances. The most likely explanations for the discrepancy between your childhood records showing "O+" and your recent test that indicated "A+" could be related to either an error in blood typing or an incorrect record in the past.
Explanation:
-
Blood Type Consistency: Blood type is determined by genetics and remains constant. It is unlikely to change unless there's a specific medical intervention such as a bone marrow transplant, which doesn't seem to apply in your case.
-
Testing Errors: The testing methods used decades ago, especially in neonatal care, might not have been as precise as they are today. Human errors in documenting or testing can also happen, leading to discrepancies.
-
Documentation Issues: It's possible that incorrect information was recorded at birth. Mistakes in labeling blood type on hospital documents, especially in the NICU with high-stress conditions, can occur.
Next Steps:
-
Confirm Your Blood Type: If you want clarity, consider getting another blood test done at a reputable laboratory. Ensure that the laboratory follows standard blood typing protocols to minimize the risk of errors.
-
Look Over Old Records: If possible, check for any previous medical records or documents that may provide additional information or confirm your current blood type.
-
Consult with a Healthcare Professional: If you have further concerns about this discrepancy or if you have other health questions related to blood type, discussing your concerns with a healthcare provider can help provide tailored guidance.

Removed a Mole at Home
I’m a 21-year-old female, and I’ve had a mole on my chest since childhood. It has been confirmed as benign, yet I’ve always felt uncomfortable about it because it was raised. This morning, I decided to take matters into my own hands and used an eyebrow razor to remove it. I realize that this wasn’t the safest approach, and it did result in quite a bit of bleeding. I managed to apply two band-aids to control it, but after taking one off for a replacement, I noticed that it’s still bleeding, albeit lightly. What should I do next?
Experiencing Sudden Jaw Discomfort and Facial Pain
As a 21-year-old male, I've developed a habit of cracking my jaw in a circular manner—something I've routinely done for years without any issues. Recently, however, I've found myself in significant discomfort. The area around my right ear and the side of my mouth are painful, making it difficult to open my mouth or even clench my teeth. This is an unusual experience for me, and I’m curious if this is something I should be worried about?
Optimal Timing for Taking Sucralfate with Other Medications
I'm a 54-year-old individual who has been on Pantoprazole, taking it twice daily for a year now. Recently, I received a prescription for Sucralfate. While I did use Sucralfate briefly last year, I was never quite confident about when to take it in relation to my other medications. During that time, which I discussed with my physician, my routine involved taking Pantoprazole one hour before meals, followed by Sucralfate prepared as a slurry thirty minutes later, with my meal occurring half an hour after the Sucralfate. Despite this plan, I keep encountering varying information on the subject and would appreciate a clearer guideline. If I plan to have dinner at 6 PM, I would like to know the ideal times for taking Pantoprazole and Sucralfate to ensure that I’m maximizing the efficacy of both medications. I’m concerned about the potential for timing to hinder their effectiveness. Thanks in advance for your help!
Availability of Rabies Vaccination in UK NHS A&E for Post-Exposure Treatment
After being bitten by a dog while traveling abroad, I completed the necessary rabies vaccination schedule as instructed (on days 0, 3, 7, and 14) and also received Human Rabies Immune Globulin (HRIG). Now that I'm back in the UK, I need to get my final vaccine dose after 28 days. Is it possible for me to visit an A&E department for this shot? Local doctor's offices do not provide this service, and the only clinics I've discovered are private travel clinics that charge upwards of £100, which is beyond my budget at the moment. My travel insurance covered the initial treatments I received in Thailand (minus the excess charge), but they will not pay for this last dose. Given that I am dealing with a post-exposure situation, isn't it reasonable to expect that I could receive this vaccine through the NHS? I was indeed bitten, and if the dog was rabid, not receiving this last dose could have severe consequences. I'm puzzled as to why the only option appears to be a costly private clinic. Can I access this vaccine through the NHS? If so, what steps should I take to obtain it? Personal details: Female, 48 years old, 172 cm tall, 70 kg in weight, bitten on the left leg by a dog, no known medical issues.
Unusual Urine Color: Is It a Concern?
A 33-year-old woman from the UK, standing at 173 cm and weighing 84 kg, not taking any medications, and leading a lifestyle free from smoking and alcohol, recently noticed a peculiar change in her urine. About an hour ago, while she was in the restroom, her urine presented a bright yellow tone, accompanied by an unexpected hint of orange creaminess. Although she plans to provide a visual reference, she is currently more concerned about some discomfort she's experiencing. Lately, she has been feeling sporadic pain in her back; at times it manifests in the lower back area and at other times below her left rib. This sensation resembles a sharp jab that fluctuates in intensity but isn't severely distressing, rating it around 4 out of 10. Aside from this, she reports no significant previous health issues. Two days prior, her urine appeared slightly cloudy, yet nothing as alarming as the current situation. After hydrating with water, the color normalized. Given these developments, she is apprehensive about the unusual urine color and seeks advice on whether consultation with a healthcare professional is warranted, particularly as her regular doctor is unavailable until the following Monday.
