Confusion Regarding Hepatitis B Testing
Recently, I underwent a blood test at MedStar Health Clinic, and the results were mostly negative. However, the Hepatitis B core antibody test returned a positive result. About a week later, I consulted my primary physician, who conducted two additional tests: HBsAg and Hepatitis B Surface Antibody (Qualitative). Both results came back negative. Following this, he advised me to receive the vaccinations, so I completed the first shot and then the second one shortly after. I’m scheduled to retest next month. I'm feeling uncertain about whether I actually have Hepatitis B. I realize it's not ideal to seek answers on social media, but I'm feeling anxious about it.

It's understandable to feel confused and anxious about your Hepatitis B testing results. Let me clarify your situation regarding the positive core antibody test and the negative other tests.
Key Points:
- Positive Hepatitis B Core Antibody (anti-HBc): This result indicates that you have been exposed to the Hepatitis B virus at some point. However, it does not confirm whether you currently have an active infection.
- Negative HBsAg Test: This indicates that you do not have an active Hepatitis B infection. The virus is not currently in your blood.
- Negative Hepatitis B Surface Antibody Test: This suggests that you do not have immunity to Hepatitis B, which is why your physician recommended vaccination.
Explanation:
The combination of your test results indicates that you may have had a past infection with Hepatitis B or been vaccinated before, but you are not currently infected. The antibodies from past exposure can sometimes remain in your system, leading to a positive core antibody test without indicating an active infection. Vaccination is recommended to protect you against future infections.
Next Steps:
- Complete Your Vaccination Series: Ensure you receive all doses of the Hepatitis B vaccine as planned. Completing the series is essential to build immunity.
- Scheduled Retesting: Attend your scheduled follow-up test next month. This will help confirm your immunity in response to the vaccinations.
- Monitor Symptoms: Keep an eye out for any unusual symptoms like fatigue, jaundice (yellowing of the skin or eyes), or abdominal pain, though these are unlikely given your current results.
Reassurance:
It's normal to feel anxious when dealing with health concerns, especially when laboratory results are complex. You've taken proactive steps by getting vaccinated and following up with your doctor. Continue to focus on your health and reach out to knowledgeable professionals with any questions or concerns you have.

Elevated Neutrophils and Decreased Lymphocytes with High ESR: What's Happening?
I am a 34-year-old woman, and I don’t smoke or consume alcohol. Currently, I am not taking any medications. Recently, I discovered that my neutrophil levels are elevated while my lymphocyte counts are low. I also have an ESR of 43, though my CRP levels are within the normal range. I'm experiencing severe pain in my bones throughout my body, along with hair loss, nerve discomfort in my arms, episodes of dizziness, feelings of nausea, reduced appetite, and overwhelming fatigue. The root cause of these symptoms remains unclear, but I feel extremely unwell and am concerned it could be indicative of a potential blood disorder.
Results from Brain MRI
To the medical team, I have obtained the findings from my recent brain MRI. As a 34-year-old woman, I've been experiencing persistent migraines. Findings highlight that all aspects appeared normal, though a note regarding slight nonspecific white matter changes was present. Naturally, I searched for information about white matter issues, and the results were rather alarming. Does this indicate the potential for early-stage dementia? Over the past two years, I've faced considerable difficulties with my memory.
Seeking Clarity on Unresolved Health Issues
My sister, a 28-year-old woman standing at 5'6" with no prior health complications, has been suffering from an unexplained illness for the last few months, leaving doctors puzzled about her condition. **Chronology of Her Symptoms:** - **April 18:** While traveling abroad, she suffered from food poisoning along with diarrhea, an issue that affected numerous travelers. In a mix-up, she ingested two Flagyl tablets instead of Imodium. - Shortly thereafter, she began to feel tingling sensations in her hands and noticed irregularities in her breathing. --- - **April 20 (Sunday):** At around 1 PM, she experienced a rapid heartbeat accompanied by shortness of breath, with an episode lasting approximately an hour. Similar episodes recurred every two days thereafter. - **April 25 (Sunday):** At 7 PM, the same symptoms returned, reaching about 80% of the intensity experienced during her most severe episode. - **April 26 (Saturday, during layover in Qatar):** Early at 6 AM on her final flight segment, she felt a tightness in her chest and struggled to get enough oxygen, rendering her unable to drink water. Paramedics who evaluated her found all vital signs normal aside from mildly elevated blood pressure. - **April 27 (UK time, Sunday):** At 2 AM, she awoke with similar symptoms again and was unable to drink water. By 3 PM, these symptoms intensified, now combined with head pressure, breathlessness, and feelings of light-headedness. - **April 28 (Monday):** Persistent symptoms continued. She found it incredibly hard to speak or take even ten steps without feeling faint. She expressed that her body seemed to be slowing down considerably. --- Since that time, her symptoms have remained unrelenting for months. Initially, her GP suspected a viral infection and suggested she wait two weeks. When her condition did not improve, they shifted to a diagnosis of anxiety. Although she is a psychologist familiar with the nuances of anxiety, she insists this isn’t just anxiety—there have been no stressors, and panic attacks do not linger for long periods. Despite following through with recommendations and collaborating with workplace psychiatrists, there has been no reversal of her symptoms. In recent weeks, her condition degenerated, prompting her to call for an ambulance three times over three months during severe episodes. Each time, preliminary examinations showed normal ECG and vital signs. Eventually, she opted to weather the episodes instead of calling for assistance. **In early July:** - The heat wave in London appeared to exacerbate her symptoms. Whereas she previously experienced a mix of good and bad days, she has faced a streak of consecutive bad days over the past 8-9 days. - She has difficulty breathing while lying on her left side and back. - Any physical activity or eating sends her symptoms spiraling—tightness in her chest, shallow breathing, and persistent dizziness that gives her the sensation of imminent fainting. - After calling 999, she was transported to A&E, where a blood test was conducted to check cardiac markers. Results revealed slightly elevated white and red blood cell counts but were deemed not clinically significant. Her hemoglobin levels were normal, and she has been taking iron supplements since her initial GP visit following her return. She was discharged with no further recommendations. In addition, she underwent a private Holter monitor test over seven days, with results expected shortly. Two days post-A&E visit (July 5): - She noticed swelling in her neck, which felt soft and visibly enlarged. - Intense jaw pain had developed over the previous days. - After reaching out to the health hotline again, she was referred back to A&E. Doctors diagnosed her with sinusitis and prescribed a regimen of penicillin four times a day. **Important Note:** Beyond this, she hasn't experienced any mucus production or cough; only pressure has been felt around her forehead and the sides of her nose. She is currently on her fourth dose of the antibiotics but hasn’t felt any improvement yet, recognizing that effects may take time to manifest. Additionally, it’s worth mentioning that about two weeks prior to the onset of her issues, she had a severe allergic reaction after taking an acne relief supplement which contained burdock root—an ingredient noted for potentially triggering severe allergic reactions. Following the administration of an antihistamine, she recovered without any lasting effects. We are seeking guidance and would greatly appreciate any insights or leads.

Understanding Recurring Illness: What Could Be Behind It?
Since August 2023, I've found myself falling ill consistently, at least once each month. Initially, I developed a cold, which spiraled into experiencing the flu and multiple bouts of strep throat between August and January. This situation necessitated an increase in medication, along with steroid treatment. Following the surgical removal of my tonsils, I felt a wave of relief. However, the reprieve was short-lived, as I soon caught another cold, and this pattern has continued thereafter. In the past, I would only become ill every couple of years, making these recent developments all the more disconcerting. Previously, these illnesses were manageable enough for me to maintain my work and daily life, but now they leave me bedridden for days, significantly impacting my professional responsibilities. The most serious episode occurred in May 2025 when I had to visit the hospital. There, I was diagnosed with a urinary tract infection, ear infections in both ears, and a sinus infection. Initially treated with antibiotics for my ears, my condition failed to improve, prompting a prescription for a stronger medication that ultimately led to recovery. After a brief period of wellness in June, I'm now facing another illness in July 2025, with both ears infected once more. As a 26-year-old woman weighing 250 pounds, I don’t smoke or drink alcohol, and I take prenatal vitamins daily, especially after a miscarriage following my May hospital visit. Medical tests reveal that my blood work is mostly normal, aside from a deficiency in vitamin D. My diet consists of a variety of fruits and vegetables. I also have polycystic ovary syndrome (PCOS) and have undergone tests for multiple sclerosis and lupus in childhood, due to experiencing occasional vision blackouts. Additionally, I had COVID-19 in 2022 but haven’t contracted it since; I am currently vaccinated with two doses for COVID-19 and received a flu shot recently.
Could My Mother Have Had a Fighting Chance with These Findings?
My mother, aged 77, stood 5 feet tall and weighed 107 pounds; she was of Filipino descent. Sadly, she passed away two weeks ago due to cardiac arrest while hospitalized in the ICU, where she was being treated for a pulmonary embolism. Prior to her passing, she received some unsettling news regarding her cancer diagnosis. Given the radiological findings below, do you think she might have had a chance to combat the illness had her demise not been so abrupt? **Cervical Spine MRI with and without Contrast** 1. Extensive metastatic spread in the spinal column without any pathological fractures observed. 2. Possible early-stage anterior epidural tumor noted at the T11, T12, L5, and S1 vertebral levels. 3. 4 mm lesion at the L1-L2 region, likely indicating either leptomeningeal metastasis or a benign schwannoma. 4. Evidence of cerebellar metastasis detected. **Brain MRI with and without Contrast** 1. A multitude of small enhancing lesions present throughout the cerebral and cerebellar areas, indicative of metastatic disease, but no major mass effect identified. 2. Linear enhancement in the left internal auditory canal, raising concern for potential metastasis. 3. Enhancing lesions in the clivus consistent with osseous metastases.
