Here is the Interpretation of the D-Dimer Test.
D-Dimer Test Result | Interpretation |
---|---|
< 243 mg/mL DDU | Normal |
> 243 mg/mL DDU | Further evaluation may be needed |
Elevated D-Dimer levels may suggest the presence of abnormal blood clots, but it's essential to consult a healthcare provider for a proper evaluation and diagnosis.
Here are some possible causes of high D-Dimer levels:
Possible Causes | Effect |
---|---|
Blood Clots | Potential risk of deep vein thrombosis (DVT) or pulmonary embolism (PE). |
Recent Surgery or Trauma | Normal response to surgery or injury. |
Infection | Possible presence of inflammation or infection in the body. |
Autoimmune Disorders | Such as systemic lupus erythematosus (SLE). |
Certain Cancers | Such as pancreatic cancer or lymphoma. |
High D-Dimer levels can indicate various conditions, and further evaluation is necessary to determine the underlying cause and appropriate treatment.
Here are some possible causes of low D-Dimer levels:
Possible Causes | Effect |
---|---|
Normal Blood Clotting | Suggests a lower risk of abnormal blood clots. |
Absence of Clot Formation | No recent clotting events or injuries. |
Absence of Inflammation | No significant ongoing inflammation in the body. |
Medications | Certain medications, like anticoagulants, may lower D-Dimer levels. |
Genetic Factors | Some individuals naturally have lower D-Dimer levels. |
Low D-Dimer levels typically indicate a reduced risk of abnormal blood clot formation, but the interpretation may vary depending on the individual's medical history and context.
