What is the Difference Between CRP and D Dimer Test?
🆚 Go to Comparative Table 🆚The main difference between CRP and D-Dimer tests lies in the substances they measure and their purposes.
CRP (C-reactive Protein) Test:
- Measures the levels of C-reactive protein in the blood.
- Used to evaluate the degree of inflammation in the body.
- Higher levels of CRP indicate inflammation, which can be caused by various factors such as infections, autoimmune diseases, or other inflammatory conditions.
D-Dimer Test:
- Measures the levels of D-dimer protein fragments in the blood.
- Used to assess blood clotting problems.
- Higher levels of D-dimer in the blood are indicative of blood clotting problems, such as deep vein thrombosis or pulmonary embolism.
In summary, the CRP test is used to measure inflammation, while the D-dimer test is used to assess blood clotting problems.
Comparative Table: CRP vs D Dimer Test
Here is a table comparing the differences between the CRP and D-Dimer tests:
Test | Purpose | Protein Measured | Inflammation Marker | Blood Clotting Marker | Normal Range |
---|---|---|---|---|---|
CRP | Measures inflammation in the body | C-reactive protein | Yes | No | Less than 10 mg/L |
D-Dimer | Measures blood clotting problems in the body | D-dimer protein fragment | No | Yes | Not applicable (binary interpretation) |
The CRP test looks for c-reactive protein in the blood sample and measures inflammation in the body. On the other hand, the D-dimer test looks for the D-dimer protein fragment in the blood sample and measures blood clotting problems in the body. The normal range for a standard CRP test is usually less than 10 mg/L, while the interpretation of D-dimer levels is binary, meaning it is either normal or abnormal.
