Indications:
This is to assess and diagnose through a blood test, an inflammatory condition.
Principle:
This protein synthesized by the liver, is present at low levels in serum normally.
Its concentration increases rapidly in case of inflammation.
Technique:
Levy of 2 mL of blood in a dry tube.
Results:
Normal values:
5 to 15 mg / L.
Pathological changes:
– A rate greater than 20 mg / L is an inflammatory or infectious reaction;
– His elevation occurs at the 12th hour to return to normal 7 to 14 days after the termination of the process.
– CRP rises much in bacterial infections that viral.
Cost:
C40.
Practical advice:
Pregnancy or estrogen-progestin therapy increased CRP levels up to 50 mg / L.
The rate is also high during the 48 hours following surgery.
A CRP testing also helps differentiate high UTI (high CRP) a low infection (low CRP).
