Recommended Tests for Evaluating Clotting Disorders

6/22/2025, 7:00:35 PMMale25-34

Male, 30 years old, height 5’6”, weight 145 pounds, not on any medications, non-smoker. After experiencing a pulmonary embolism following an extended flight, my hematologist suggested conducting tests to identify potential causes. I think he intended to include genetic assessments in the process. Since relocating to a new state, finding another hematologist has a long wait time, and I’m willing to cover the cost of tests that might help, particularly as my job requires frequent air travel. I would greatly appreciate guidance on which tests might be beneficial for me. Here’s a list of tests I've discovered thus far. Are there additional ones I should consider? - Prothrombin Time (PT) and International Normalized Ratio (INR) - Partial Thromboplastin Time (PTT) and Activated Partial Thromboplastin Time (aPTT) - Fibrinogen Level - Complete Blood Count (CBC) - Factor V Leiden mutation test - Prothrombin Gene Mutation test If there’s a more suitable subreddit for this inquiry, I would appreciate your recommendations. Thank you for your help!

It’s great that you're proactive about understanding and managing your health, especially after a significant event like a pulmonary embolism. Here’s a summary of important testing recommendations for evaluating clotting disorders, particularly given your situation of frequent air travel.

Key Tests for Evaluating Clotting Disorders

  1. Coagulation Tests:

    • Prothrombin Time (PT) and INR: Measures how long it takes your blood to clot.
    • Partial Thromboplastin Time (PTT): Assesses the blood's clotting ability through a different pathway.
    • Fibrinogen Level: Evaluates the level of fibrinogen, a protein involved in blood clotting.
  2. Genetic Testing:

    • Factor V Leiden Mutation Test: Identifies if you have a genetic mutation that increases your risk of developing abnormal blood clots.
    • Prothrombin Gene Mutation Test: Detects another genetic variant associated with increased risks of clotting.
  3. Complete Blood Count (CBC): Although it provides general information about your blood cells, it will help rule out other conditions.

Additional Tests You Might Consider

Given your history of pulmonary embolism and the potential for frequent air travel, here are a few additional tests that might be considered, depending on your clinical situation:

  • Antiphospholipid Antibodies: To check for an autoimmune condition that can increase clotting risk.
  • Protein C and Protein S Levels: These proteins help regulate blood clotting; deficiencies can lead to increased clotting risk.
  • Antithrombin III Level: Evaluates another important protein that helps prevent blood from clotting too much.

Prioritized Next Steps

  1. Confirm with Your Hematologist: Before proceeding, it's best to discuss these additional tests with your hematologist, if possible. They can help determine which tests are most relevant in your case, especially considering your history.

  2. Get the Suggested Tests Scheduled: Aim to have the coagulation tests and genetic testing conducted, as these will provide key insights into your clotting risk.

  3. Consider a Second Opinion: If wait times for hematology consultations are long, consider seeking a second opinion from another healthcare provider or a specialist in a nearby city.

  4. Maintain Awareness of Symptoms: Monitor for any symptoms related to blood clots, such as swelling, pain in the legs, or shortness of breath, and seek immediate care if these occur.

  5. Stay Hydrated and Move Regularly During Travel: While you are working on these tests, ensure to hydrate well and move around during flights to help reduce your risk of another embolism.

You’re taking a responsible approach to your health, and I wish you the best in your journey towards understanding and managing your condition. If you have further questions about these tests or how to manage your risk, feel free to ask.

Strange Jelly-Like Substance Observed from Wound

I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.

Strange Stomach Sensation Leading to Waking Up

Greetings. I'm a 36-year-old male, standing at 172 centimeters and weighing 90 kilograms. I don't take any medications, nor do I smoke. I've been living with diastasis recti for several years now, and I may also have irritable bowel syndrome (IBS). Additionally, I deal with fatty liver and kidney stones, though I assume these last two conditions are not related to my current concern. Occasionally, I experience a peculiar sensation that jolts me awake; it feels like a quick pulsing in my stomach. I’ve noticed it tends to affect the left side when I’m lying on my left side and the right side when on my right. Remarkably, it can occur even when I’m on my back. This strange feeling often escalates into a surge that fully rouses me. Alongside this, I sometimes feel prickling sensations throughout my body and fleeting lightheadedness. When this sensation disturbs my sleep while I’m turned to my side, shifting onto my back or the opposite side might alleviate it, but not always. In instances where I awaken while lying on my back, I discovered that gently pressing my hands on either side of my stomach can help, as can rising to a sitting or standing position. However, during my last two episodes—one a couple of weeks ago and another tonight—those techniques weren’t effective right away, which made me feel a bit anxious, prompting me to seek advice. Does anyone have insight into what might be going on? By the way, I’ve undergone routine ultrasound examinations of my abdomen by two different physicians during check-ups, both of whom assured me that everything appears normal, including my abdominal aorta and internal organs. They didn’t identify any issues at that time.

Understanding Tuberculosis Exposure Risk

A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.

24M | Unexplained Fainting Incident

**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
