CRP Normal Range

CRP normal range! CRP levels may be elevated in people who have certain types of cancer, heart disease, diabetes, kidney disease, and infections.

CRP Normal Range

CRP Normal Range in mg/l

  • CRP is measured in the blood from a serum sample that is sent to a laboratory for analysis.
  • Traditionally, CRP levels have been measured within the 3 to 5 mg/L range in assessing for inflammation.
  • High sensitivity CRP (hs-CRP) tests able to measure down to 0.3 mg/L which is necessary for risk assessment for the vascular disease.

The outlook on elevated c-reactive protein depends on the associated factors causing it. In terms of cardiovascular disease, lower levels of c-reactive protein may be associated with a lower overall risk of disease and a better outlook for the patient.

CRP Normal Range mg/dl

CRP Normal Range mg/dl – This standard CRP test is not to be confused with a hs-CRP test. These are two different tests that measure CRP and each test measures a different range of CRP level in the blood for different purposes:

  • The standard CRP test measures high levels of the protein observed in diseases that cause significant inflammation. It measures CRP in the range from 8 to 1000 mg/L (or 0.8 to 100 mg/dL).
  • The hs-CRP test precisely detects lower levels of the protein than that measured by the standard CRP test and is used to evaluate individuals at risk of cardiovascular disease. It measures CRP in the range from 0.3 to 10 mg/L. (See the article on hs-CRP.)

What is the CRP Test?

What is the crp test? C-reactive protein (CRP) is a protein made by the liver. CRP levels in the blood increase when there is a condition causing inflammation somewhere in the body. A CRP test measures the amount of CRP in the blood to detect inflammation because of acute conditions or to monitor the severity of disease in chronic conditions.

The CRP test is not diagnostic, but it provides information to your doctor whether inflammation is present without identifying the source of the inflammation. This information can be used with other factors such as signs and symptoms, physical exam, and other tests to determine if you have an acute inflammatory condition or are experiencing a flare-up of chronic inflammatory disease. Your doctor may then follow up with further testing and treatment.

The CRP test is useful in monitoring chronic inflammatory conditions to detect flare-ups and to determine if treatment is effective. Some examples include;

  • Inflammatory bowel disease
  • Some forms of arthritis, including rheumatoid arthritis
  • Autoimmune diseases, such as lupus or vasculitis
  • COVID-19 treatment
  • The CRP test is widely used to detect sepsis in newborn babies.
  • The CRP test may monitor patients after surgery. CRP levels increase after surgery and drop to normal unless a post-surgery infection is present.
  • CRP can be a good predictor of rejection in kidney transplant recipients.

CRP may sometimes be advised along with an erythrocyte sedimentation rate (ESR), another test that detects inflammation, or pro-calcitonin, a test that shows sepsis. While the CRP test is not specific enough to diagnose a particular disease, it serves as a general marker for infection and inflammation, thus alerting the doctor that further testing and treatment may be necessary. Depending on the suspected cause, some other tests may be performed to identify the source of inflammation.

CRP Normal Range in Covid-19

Why are doctors recommending CRP tests even for patients in home isolation?

C-reactive protein (CRP) test is mainly conducted for patients who are hospitalised for Covid virus treatment, but many doctors are recommending the same test even to those Covid positive patients who are in home isolation with moderate to mild symptoms. CRP is not a diagnostic test, but it has prognostic value.

Doctors are conducting it mandatorily for the patients with critical conditions who are in hospital care because it is one indicator showing the body’s reaction to the ongoing treatment.

If the CRP, which is also recommended in the guidelines for Covid treatment, is normal then the patient’s body is reacting to the treatment positively and if it is higher than required, then doctors need to check the infection level in the body through other tests like CT scan. It is recommended for those in home isolation too if they do not show any improvement in their symptoms even after the passing of a week.

Doctors say that for patients with mild Covid symptoms, CRP is unnecessary unless the patient is suffering from the same symptoms even after passing of 5 days of his/her contracting the virus. Doctors recommend it for at least twice on an interval of 4-5 days just to check the inflammation to judge about the further complication level.
