Understanding Hepatitis B Immunity Fluctuations
Greetings, Doctors! I’m a 30-year-old Caucasian woman residing in Australia, standing at 5'3" and weighing approximately 125 lbs, with no significant health concerns in my history. During my most recent two sexual health screenings, I received negative results for hepatitis; however, the medical staff advised me to consider a booster shot because I was not presenting as immune. I recently underwent serology testing to assess my vaccination status for hepatitis, planning to initiate a treatment regimen if necessary. Surprisingly, the results indicated that I am indeed immune. I completed the hepatitis vaccination series in infancy, so I’m puzzled as to why my previous sexual health evaluations suggested otherwise. Could this fluctuation in immunity be influenced by various health factors?

It's great that you are proactive about your health and seeking clarity regarding your hepatitis B immunity. Based on your situation, let's break down a few important points.
Main Points:
- Hepatitis B Immunity: Your body can produce an immune response after vaccination, but fluctuations in immunity can occur.
- Serology Testing: These tests can sometimes yield varying results based on timing, the type of immunity being tested, or lab errors.
- Follow-Up Actions: It's essential to understand your immunity status and consider booster recommendations.
Explanation:
Hepatitis B immunity can be influenced by several factors, including:
- Time since Vaccination: Immunity may wane over time for some individuals, although many maintain adequate protection long-term.
- Test Specifics: Different types of serology tests measure different aspects of immunity (e.g., presence of antibodies). A poor immune response may not be accurately reflected in every test.
- Health Factors: Conditions that affect your overall immune system (like certain chronic illnesses or medications that suppress your immune system) can influence your immunity levels.
The fact that your recent testing shows immunity suggests that you are still protected against hepatitis B, which is reassuring. The previous negative results could have been due to timing or specific test factors.
Next Steps:
- Clarify With Your Provider: Ask your healthcare provider about the specific tests used in your previous screenings and how they differ from the serology test that showed immunity.
- Consider a Booster: Based on medical guidelines, if there's any uncertainty about your immunity or if more than 10 years have passed since your initial vaccinations, a booster may still be beneficial.
- Regular Screening: Continue with regular sexual health screenings as a part of your routine healthcare to monitor for any changes in your health status.
This proactive approach will help ensure you maintain your immunity and overall health. If you have further questions or concerns, feel free to ask!

Understanding Low Blood Count & Family History: What's Next?
I have a concern regarding consistently low blood counts and a notable family medical background. In recent discussions, my healthcare provider hasn't proposed any recommendations for further investigation despite ongoing trends. Lately, my blood tests have shown that the white blood cell count (WBC) is consistently near the lower threshold of normal, along with hemoglobin (HGB) and hematocrit (HCT) values that are either at the lower limit or slightly below it. Other components of the complete blood count (CBC) appear to be within normal ranges. Over the past several years, results indicate a persistent, mild case of leukopenia and anemia. My family history is particularly alarming: my father battled Refractory Anemia with Excess Blasts (RAEB), which falls under the umbrella of Myelodysplastic Syndrome (MDS). His condition progressed to the point where he required weekly blood transfusions and underwent chemotherapy to delay the onset of leukemia until his eventual passing. Given this context, I am questioning whether I should undergo further diagnostic testing or if annual blood tests suffice. An early diagnosis of MDS is known to lead to improved treatment options and potentially curative solutions, such as a bone marrow transplant. Here’s a breakdown of my relevant blood test results: **Red Blood Cells (RBC)** - **Date:** October 8, 2024 | **Value:** 4.49 x 10^12/L | **Normal Range:** 4.32 - 6.1 x 10^12/L - **Date:** April 2, 2024 | **Value:** 4.68 x 10^12/L | **Normal Range:** 4.32 - 6.1 x 10^12/L - **Date:** September 21, 2023 | **Value:** 4.74 x 10^12/L | **Normal Range:** 4.32 - 6.1 x 10^12/L - **Date:** March 23, 2023 | **Value:** 4.59 x 10^12/L | **Normal Range:** 4.32 - 6.1 x 10^12/L - **Date:** April 15, 2022 | **Value:** 4.69 x 10^12/L | **Normal Range:** 4.32 - 6.1 x 10^12/L **White Blood Cells (WBC)** - **Date:** October 8, 2024 | **Value:** 3.9 x 10^9/L | **Normal Range:** 3.8 - 10.7 x 10^9/L | **Notes:** Borderline - **Date:** April 2, 2024 | **Value:** 3.6 x 10^9/L | **Normal Range:** 3.8 - 10.7 x 10^9/L | **Notes:** Low - **Date:** September 21, 2023 | **Value:** 4.3 x 10^9/L | **Normal Range:** 3.8 - 10.7 x 10^9/L - **Date:** March 23, 2023 | **Value:** 3.9 x 10^9/L | **Normal Range:** 3.8 - 10.7 x 10^9/L | **Notes:** Borderline - **Date:** April 15, 2022 | **Value:** 4 x 10^9/L | **Normal Range:** 3.8 - 10.7 x 10^9/L **Hemoglobin (HGB)** - **Date:** October 8, 2024 | **Value:** 13.5 g/dL | **Normal Range:** 13.5 - 18 g/dL | **Notes:** Borderline - **Date:** April 2, 2024 | **Value:** 14.2 g/dL | **Normal Range:** 13.5 - 18 g/dL - **Date:** September 21, 2023 | **Value:** 14.2 g/dL | **Normal Range:** 13.5 - 18 g/dL - **Date:** March 23, 2023 | **Value:** 13.8 g/dL | **Normal Range:** 13.5 - 18 g/dL - **Date:** April 15, 2022 | **Value:** 13.9 g/dL | **Normal Range:** 13.5 - 18 g/dL **Hematocrit (HCT)** - **Date:** October 8, 2024 | **Value:** 40.7% | **Normal Range:** 42 - 52% | **Notes:** Low - **Date:** April 2, 2024 | **Value:** 42% | **Normal Range:** 42 - 52% | **Notes:** Borderline - **Date:** September 21, 2023 | **Value:** 41.9% | **Normal Range:** 42 - 52% | **Notes:** Low - **Date:** March 23, 2023 | **Value:** 41.3% | **Normal Range:** 42 - 52% | **Notes:** Low - **Date:** April 15, 2022 | **Value:** 42.4% | **Normal Range:** 42 - 52% | **Notes:** Borderline
Swelling of the Face Following Sun and Sea Exposure
Hi everyone, I’m a 30-year-old female. Recently, after spending time in the sun and swimming in the ocean, I noticed that my forehead had become puffy. I visited the emergency department yesterday, where I was administered two IVs, one with cortisone. While the swelling on my forehead subsided, I just realized that the area between my eyes and nose is beginning to swell as well. Now it appears as though my eyes are spaced farther apart than usual. Five years ago, I had a similar incident, and during that time, the IV treatment I received effectively resolved the issue. I initially thought this recent treatment had the same effect, but now the swelling seems to be returning. Is this a normal reaction? Additionally, I should mention that the swelling appeared after I consumed something salty. Should I consider going back to the emergency room?
Are There Tests Available for Detecting Poisons and Medications?
I have a partner who is heavily invested in unconventional and potentially harmful alternative therapies. She frequently uses substances such as hydroxychloroquine, ivermectin, turpentine, and even bleach diluted in water. This has been happening behind my back, as I have voiced strong objections to these practices. While I believe she is not currently administering these substances to our children, I cannot completely dismiss the possibility. At this time, I haven't noticed any signs that would indicate my children are affected, but I'm still concerned. If I were to consult with a healthcare professional, would there be any tests available that could reveal if my kids have ingested these substances? My eldest child is an 8-year-old boy, weighing around 65 pounds, and I'm simply looking for some reassurance.
Could Petechiae Indicate Low Platelet Levels?
I'm a 21-year-old female and I've been monitoring my blood pressure frequently over the past few days. Recently, I experienced a significant weight loss of around 75 pounds due to using a GLP-1 medication, and I'm uncertain if this has impacted my blood pressure readings. The other day, specifically Thursday, I measured my blood pressure four times on each arm, and shortly after, I noticed several petechiae lines developing on both arms, which thankfully faded by the next day. When I checked my blood pressure again, I felt discomfort as the cuff inflated to a high level, leading to the appearance of purple streaks and more petechiae. This has left me wondering whether I could have low platelet counts or possibly leukemia. I've read that experiencing this is not typical, and it has made me anxious; I’m seeking some reassurance on this matter.
Seeking Advice on a Leg Infection Concern
Hello all, I'm a 25-year-old woman. Last Sunday, I discovered an unusual issue on my leg. The problem first caught my attention the night before, as it was intensely itchy. It wasn’t until I was in the shower that I really took a good look at it. Unsure of what was happening, I decided to give it some time, only cleaning it with Dacan and applying some fusidic acid ointment. The following day, Monday, I noticed it had visibly worsened. Concerned, I visited my doctor and underwent some blood tests, which indicated a white blood cell count of 8.406 (10^3/ uL) and a CRP level of 18 mg/L. The doctor suggested I might be in the very early stages of erysipelas— I'm not sure of the English term for that condition. I was prescribed antibiotics—specifically Amoxicillin, to be taken at a dosage of 2 grams three times daily, as I am on the heavier side. Now fast forward to Tuesday, it has been about a day since I began the treatment. I have already taken 6 grams of the medication (which is the total for today). This morning, I woke up to find that the infection seemed larger and had spread to a larger area of my skin. I took my most recent dose about an hour ago, and to my surprise, the redness has significantly diminished. I even marked the area with a marker to keep track of any changes. I'm uncertain about the effectiveness of the antibiotics. Thankfully, I’m not experiencing fever or pain, and the itching has subsided quite a bit. However, the affected skin still feels warm and somewhat tight, although not as tight as it did yesterday. I'm worried that the area of redness appears greater than before. What should my next steps be? My doctor mentioned that if there’s no improvement within 48 hours, we might switch to Augmentin. However, I tend to worry excessively about my health. Are the doctors handling this correctly? Is it accurate that this situation is still classified as early stage? I made the error of reading about cellulitis, and now I can't get it out of my mind. I appreciate any advice you can provide!
