Seeking Clarity on Unusual Bloodwork Findings
**Symptoms Experienced**: Frequent bruising along veins, increased skin sensitivity, and occasional headaches accompanied by transient confusion or memory loss. These symptoms manifest in connection with autoimmune flare-ups and show improvement after a five-day course of prednisone. **Current Medications**: Hydroxychloroquine, Sulfasalazine, Metoprolol. **Family Medical History**: There has been a prevalence of strokes on the maternal side at the age of 47 throughout the last three generations, as well as issues related to miscarriage and difficulties in maintaining pregnancy. **Laboratory Results**: * **Standard Test Results**: - Lupus Anticoagulant/Antiphospholipid Profile: Within normal range - von Willebrand Factor: Normal - Factor VII, IX, XI, XII: All within normal limits - Hemochromatosis: Normal - Tryptase Levels: Normal - Protein S and C: Both normal - D-Dimer: Normal - MPL and CALR: Normal - PAI-1 Gene: 4G/5G - Iron studies including TIBC, Ferritin, and Testosterone: Normal * **Abnormal Results during Flares**: - APTT: Prolonged - PT: Prolonged - Thrombin Time: Prolonged - Thrombin Time (Heparin Neutralized): Prolonged - Fibrinogen Activity: Low - Fibrinogen Antigen: Normal - Euglobulin Lysis Time: Shortened * **Abnormal Results Post-Flare**: - Thrombin Time: Prolonged - Thrombin Time (Heparin Neutralized): Prolonged - Fibrinogen Activity: Normal - Fibrinogen Antigen: Low **Inquiries**: 1. How should one interpret the transition from low fibrinogen activity during flares to low fibrinogen antigen after flares? Could this variation be partially attributed to an inflammatory response? Is that a plausible interpretation? 2. Are the observed elevations in thrombin time (both TT and TT-HN) indicative of any specific health conditions or disorders? How do they relate to fibrinogen activity and antigen levels? 3. Does this pattern of lab results pose any potential risk for thrombotic complications?

Overview: Your lab results and symptoms suggest complex interactions involving inflammation and coagulation. The transitions in fibrinogen levels and prolonged thrombin times merit careful consideration, particularly regarding any potential risks and their implications for your health.
Explanation
-
Fibrinogen Variations: Fibrinogen is a protein involved in blood clotting. The transition from low fibrinogen activity during flares to low fibrinogen antigen after flares can indeed reflect an inflammatory response. During active inflammation, fibrinogen may become consumed, leading to low activity. However, this could result in a situation where despite low activity, the antigen (which indicates the presence of the protein) remains normal until after the flare subsides.
-
Elevated Thrombin Times: Prolonged thrombin times can indicate issues with clotting, potentially pointing to conditions like disseminated intravascular coagulation (DIC) or liver dysfunction, among others. These elevations—especially when coupled with fluctuating fibrinogen levels—suggest that your coagulation pathways are being affected, likely due to the inflammatory states caused by your autoimmune condition.
-
Potential Risk for Thrombotic Complications: The pattern of prolonged thrombin times, combined with fluctuating fibrinogen levels, may suggest an increased risk for both clotting and abnormal bleeding. While your results like the D-Dimer level being normal is reassuring and lessened some immediate concerns regarding thrombosis, the prolonged thrombin time is something that should be monitored closely.
Next Steps
-
Monitor Symptoms Closely: Keep track of your symptoms, particularly any changes in bruising, headache frequency, and cognitive symptoms during flare-ups. Noting specific triggers or patterns can help in managing your condition better.
-
Lifestyle Adjustments: Incorporate a balanced diet, rich in anti-inflammatory foods (like leafy greens, fatty fish, nuts, and berries), and ensure you stay well-hydrated. These can help in reducing inflammation and supporting overall well-being.
-
Regular Blood Testing: Schedule regular follow-ups for lab tests to monitor fibrinogen levels and thrombin time, especially during flare periods. This will help your healthcare provider assess the situation more accurately.
-
Education and Support: Consider accessing educational resources specific to lupus and autoimmune conditions. This can empower you with knowledge on what to expect and how to manage symptoms effectively. Connecting with support groups may also provide emotional support and shared experiences.
-
Discuss with Healthcare Provider: If you haven’t already, discuss these lab results and concerns with your healthcare provider. They can offer more tailored advice and possibly adjust your treatment plan to manage both your autoimmune flare-ups and coagulation concerns effectively.

Navigating Health Challenges: Seeking Further Options
At the age of 25, I find myself grappling with a perplexing set of health issues that have persisted for the past three years. My experiences include uncertain symptoms such as blurred vision, uncontrollable shaking, numbness in my hands and feet, frequent headaches, persistent nausea, bouts of dizziness when standing, severe lower back discomfort, muscle weakness, and gastrointestinal troubles. Despite undergoing a wide range of medical evaluations—including blood tests, stool tests, urinalysis, MRIs, CT scans, X-rays, and ultrasounds—the results consistently yield normal readings, aside from the diagnosis of a Chiari malformation for which I had surgery in April. Unfortunately, this procedure has not alleviated my symptoms; in fact, they seem to have intensified following the surgery. Given that my test results do not indicate any concerning issues, it appears that physicians are limited in their ability to assist me further. I’m now wondering what my next steps should be. Are there specialists out there who might offer additional insight or treatment? Am I simply out of options? My symptoms are so debilitating that they severely restrict my capacity to work even part-time and manage my daily life effectively.
Understanding Bile Duct Strictures
A 46-year-old female, measuring 165 cm in height and weighing 87 kg, previously smoked but has not done so in over 15 years and is currently not on any medications. She recently underwent a cholecystectomy following persistent episodes of biliary colic and one occurrence of pancreatitis. Post-surgery, it was discovered that she has a stricture in the common bile duct (CBD). After undergoing several ERCP procedures, a plastic stent was placed via endoscopic ultrasound (EUS). However, tests including MRI, dotatate PET, and biopsy yielded inconclusive results. The stricture is described as small, located at the mid CBD, exhibiting hyperenhancement with a dilated vessel present on the mucosal layer and was found to be eccentric. Blood tests have all returned to normal levels, with prior liver function tests that were abnormal now stabilized. The surgeon has suggested proceeding with surgery to address the CBD, potentially involving a hepaticojejunostomy. There is a concern regarding whether the stricture may have originated from a stone that migrated from the gallbladder. Given the current normal blood work and the uncertainty surrounding the test results, would it be prudent to adopt a watchful waiting approach, or might there be additional tests worth pursuing? Prior to the cholecystectomy, the patient experienced multiple biliary colic incidents and the gallbladder was noted to contain several stones. I appreciate any insights you may offer on this matter.
Struggling with Chronic Health Issues and Loss of Insurance: Seeking Guidance
Greetings, I’m a 26-year-old woman from the USA, weighing 138 pounds and standing at 5’3”. I’m currently on a daily regimen that includes oral birth control and Zofran 8mg taken three times a day. Recently, I completed a 90-day treatment with pantoprazole. I have several diagnosed health conditions, including gastritis, GERD, IBS, which has manifested as chronic constipation, as well as me/cfs, arthritis, and visceral nerve hypersensitivity. My primary care provider believes I might have endometriosis, but I can’t afford the necessary surgery for a definitive diagnosis. I experience persistent constipation alongside early fullness, nausea, acid reflux, digestive discomfort, abdominal pain, low blood pressure, and difficulty tolerating a variety of foods and drinks. Occasionally, I also encounter breathing difficulties and profound body weakness, along with feelings of fatigue and tingling sensations in my hands. An endoscopy performed last year revealed mild gastritis, with tests showing no evidence of H. Pylori or celiac disease. Countless blood tests have yielded unremarkable results, and a CT scan with contrast produced no findings of significance. My blood pressure typically hovers around 100/70, with a noted low of 84/62 that caused dizziness and extreme fatigue. This health journey began in 2020 following a COVID-19 infection. I endured 18 days of severe illness without needing hospitalization, but in the months that followed, my health deteriorated significantly, leaving me bedridden for an extended period. It took four years until I could return to work and eat without difficulty. I adhere to a low FODMAP diet due to my dietary restrictions. I avoid processed foods, excessive fats, and sugars. My usual meals consist of simple items like plain scrambled eggs, nonfat Greek yogurt, fresh white bread, peaches, grapes, carrots, and lean meats such as chicken and turkey lunch meat. Despite being deemed safe, these foods often trigger stomach upset. Small portions are all I can manage before feeling uncomfortably full; if I go too long without food, nausea sets in. Hydration is challenging since drinking too much water induces reflux and regurgitation, so I supplement with sugar-free Powerade for hydration and electrolytes. Occasionally, I enjoy hot ginger tea. A single indiscretion in my diet can lead to prolonged nausea lasting over six hours. Nighttime brings its own challenges as I frequently wake up with burning in my throat from acid reflux, a condition so severe it has led to the loss of several teeth due to enamel erosion. I recently finished a 90-day course of pantoprazole, which initially reduced acid levels but seemed to lose efficacy toward the end. Additionally, I suffer from recurrent nightmares, though I’m unsure if there is a connection. My physical capabilities are limited; standing for more than 20 minutes brings on pain and weakness in my legs, and I struggle to lift heavy objects. Exercise is exceptionally taxing for me, leaving me perpetually fatigued. I often sleep 10 to 12 hours a night and spend upwards of 12 hours a day in bed, which is an improvement compared to two years back when I was typically in bed for 18 or more hours daily. While I manage to hold a job, my capacity is constrained, as exertion frequently leaves me exhausted or ill, necessitating the use of a cane on days when leg weakness is particularly pronounced or when I need to walk more than usual. This ongoing struggle feels exhausting; I’m frustrated by my constant fatigue and the limited variety of foods I can consume, even those often distress my digestive system. My daily life is restricted compared to others, and this burden weighs heavily on me mentally. After turning 26 and losing my insurance, I face additional setbacks as my primary care physician plans to retire soon. He was pivotal in recognizing the seriousness of my situation, unlike many others I consulted for years with little progress. I find myself at a crossroads, uncertain of the next steps or what precisely is affecting my health. My PCP hinted that there might be other undiagnosed issues but couldn’t pinpoint exactly what they are. I’ve applied for Medicaid, though navigating the process in my state is daunting. More than anything, I desire to improve my health and seek clarity on how to achieve this. Thank you for taking the time to read my story.
Managing Minor Anal Bleeding: What You Should Know
At the age of 17, I find myself weighing 83 kg and measuring 164 cm. Recently, I experimented with anal stimulation but, lacking proper sex toys, I resorted to using nearby objects. Unfortunately, the shape of these items caused some irritation during withdrawal, resulting in minor bleeding when I wiped. The bleeding has significantly decreased since then, though I experienced slight discomfort. What steps can I take to promote better healing? Should I seek medical advice?
Assessing the Severity of Hip Osteoarthritis Through X-rays
Greetings, I am a 38-year-old male. In January 2025, I underwent X-rays of my hips due to persistent discomfort on the sides of both hips that had lasted for several months. In addition to the X-rays, an MRI was conducted in April 2025. The findings revealed that the cartilage layer remains intact, with no signs of osteophytes or cysts present. The physician informed me that I am experiencing early stages of osteoarthritis, suggesting that a joint replacement is unlikely to be necessary in the near future. He indicated that my pain is likely originating from the greater trochanter, despite the MRI not showing any signs of inflammation. When I compare my images to those of other hips, it appears to me that there is minimal cartilage left, almost as if it is just a thin covering. Do you believe that this condition is merely in its early stages of OA, or could it already be considered advanced? My physiotherapist has expressed concerns that the joint may be nearing its limits. I appreciate any insights you may have. Thank you for your feedback!
