Low clinical probability. If negative D-dimer, PE is excluded. If positive D-dimer, obtain MDCT and base treatment on results. Moderate clinical probability. If negative D-dimer, PE is excluded. However, the authors were not concerned that a negative MDCT with negative D-dimer in this setting has a 5% probability of being false. Presumably, the ...
D-dimer (or D dimer) is a dimer that is a fibrin degradation product (FDP), a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. It is so named because it contains two D fragments of the fibrin protein joined by a cross-link , hence forming a protein dimer .
Less common causes include snake bites, frostbite, and burns. [1] There are two main types: acute (rapid onset) and chronic (slow onset). [1] Diagnosis is typically based on blood tests. [2] Findings may include low platelets, low fibrinogen, high INR, or high D-dimer. [2] Treatment is mainly directed towards the underlying condition.

Imaging is also needed for hospital inpatients with suspected DVT and those initially categorized as unlikely to have DVT but who have a positive D-dimer test. [1] While the Wells score is the predominant and most studied clinical prediction rule for DVT, [39] [115] it does have drawbacks. The Wells score requires a subjective assessment ...
Antiphospholipid syndrome is known for causing arterial or venous blood clots, in any organ system, and pregnancy-related complications.While blood clots and pregnancy complications are the most common and diagnostic symptoms associated with APS, other organs and body parts may be affected like platelet levels, heart, kidneys, brain, and skin.
Every year, millions of women get mammograms to screen for breast cancer. About 10% of them are called back for further testing. And 7% to 12% of those women receive a false-positive result ...
