D- dimer. Checking D-dimer is a screening test for blood clot in an appropriate setting where the pretest probability is higher. The blood tests used to idenify some causes of blood clots include hypercoagulability tests (eg, factor V Leiden, protein C, protein S, anti thrombin III), antiphopspholid antibody etc. Based on risk factors and pretest probabily your doctors may choose a differernt blood tests.
It depends. After a patient is diagnosed with a blood clot that is unexplained for example your doctor would perform an age appropriate work-up for other possible causes of blood clots, also depending on your age and family history it would be appropriate to order other specific tests to establish risk of recurrence. The list of tests can be extensive and costly on the patient.
D-dimer. Checking D-dimer is an initial screeing blood test followed by an imaging study (dulpex US or CTA) to confirm blood clots. Hypercoagulablity tests (eg, factor V Leiden, protein C, protein S, Antithrombin III), anti-phospholipid antibody etc are used to identify the cause of DVT in appropriate settings. Based on risk factors your doctor may chose a test to identify the cause of a blood clot.
Can a dr find out, that a person have blood clots or a thyroid problem even of they weren't looking for it in your blood work?
Yes. If you do a CBC or cell blood count and a thyroid test like TSH you can find these problems if you were having these tests done as a routine screening.
Sometimes. Your medical history, symptoms and physical examination could suggest the presence of a thyroid disease or a DVT or PE, which your doctor will order specific test to confirm or eliminate his suspicion.
ER on Sunday. They ran ct, ekg, blood work for dizziness and rapid heart beat. No blood clots and heart was fine. I'm still so dizzy should I go back?
Primary care. That will be at typical office visit, due to the type of work-up that is typically done in Er that will sort out life threatening conditions but will leave you with no answers to your actual condition. Urgent care would be a different option. Hope this helps.
