Blood test is an important laboratory analysis performed on a blood sample.
Presence of various harmful chemicals, poison and even drugs can be determined through the blood test. Differences in the quantities and proportions are determined. The difference in the proportion of various vital metabolites and constituents in the blood help in identifying the presence of various ailments of the body. The analysis is usually performed by comparing the amount of various chemical entities present in the blood under test to the standard ratio of one or more chemical entities that are actually supposed to be present in the blood. It also performs many regulatory functions like the regulation of body pH of the body and also the regulation of core body temperature. Other than this the blood being the only liquid majorly circulating in the body also performs the important hydraulic functions. They also help in determining the presence of pathogens in the body. Blood tests are mainly used to determine physiological and biochemical states, such as disease, mineral content, drug effectiveness, and organ function. The regulation of the internal body temperature despite the changes in the outside atmosphere is particularly important in the warm blooded animals. This sample is usually extracted from a vein in the arm using a needle or via a finger-prick. It is therefore important that the reports of the blood test and the lab test results are properly understood by the patient so that he/she has a clear understanding of the ailment of the body.

Those are signs of inflammation. Inflammation can be acute (sudden) and temporary. Chronic inflammation can also happen if your tissues are repeatedly injured or irritated, for example from smoking or chemicals in the environment.
A CRP test can show whether you have inflammation in your body and how much. But the test can't show what's causing the inflammation or which part of your body is inflamed.This type of inflammation is usually helpful. For example, if you cut your skin, it may turn red, swell, and hurt for a few days. Normally, you have low levels of c-reactive protein in your blood. Chronic infections, certain autoimmune disorders, and other diseases can cause harmful chronic inflammation. A c-reactive protein test measures the level of c-reactive protein (CRP) in a sample of your blood. Your liver releases more CRP into your bloodstream if you have inflammation in your body. This is called chronic (long-term) inflammation. High levels of CRP may mean you have a serious health condition that causes inflammation.
Inflammation is your body's way of protecting your tissues and helping them heal from an injury, infection, or other disease. CRP is a protein that your liver makes. Inflammation can also happen inside your body.
If inflammation lasts too long, it can damage healthy tissues.
