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 .
Principles of D-dimer testing. Fibrin degradation products (FDPs), also known as fibrin split products, are components of the blood produced by clot degeneration. [1] Clotting, also called coagulation, at the wound site produces a mass of fibrin threads called a net that remains in place until the cut is healed. As a cut heals, the clotting ...
Antibiotic sensitivity testing provides information about which antibiotics are more likely to be successful and should therefore be used to treat the infection. [1] Antibiotic sensitivity testing is also conducted at a population level in some countries as a form of screening. [4]
In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate). If 100 patients known to have a disease were tested, and 43 test positive, then the test has ...
log(Diagnostic Odds Ratio) for varying sensitivity and specificity. In medical testing with binary classification, the diagnostic odds ratio (DOR) is a measure of the effectiveness of a diagnostic test. [1] It is defined as the ratio of the odds of the test being positive if the subject has a disease relative to the odds of the test being ...
Diagnostic coding is the translation of written descriptions of diseases, illnesses and injuries into codes from a particular classification. In medical classification, diagnosis codes are used as part of the clinical coding process alongside intervention codes. Both diagnosis and intervention codes are assigned by a health professional trained ...
Functional drug sensitivity testing (f-DST) is an in-vitro diagnostic test method in functional precision medicine. [1] It was developed to personalize the choice among cytotoxic drugs and drug combinations for patients with an indication for systemic chemotherapy in specific cancer types.
D-Dimer is not specific to DVT therefore all clinical details should be considered before making a diagnosis It is not specific for anything. JFW | T@lk 19:06, 26 November 2006 (UTC) Specificity (as in "sensitivity and specificity" of a test) has nothing to do with whether the test is specific to one disease as opposed to other diseases.
