<\/span>Introduction<\/strong><\/span><\/h2>\n\n\n\nWhen we are dealing with infections, inflammation, and different diseases, laboratory tests are of great help. They aid in correctly diagnosing health concerns. Two frequently used tests, the C-reactive protein (CRP)<\/a> test, and the erythrocyte sedimentation rate (ESR)<\/a> test can detect inflammation 1<\/a><\/sup>. Each of them plays a unique role in detecting inflammation and monitoring a disease. \u00a0On the contrary, there are distinct differences between them 2<\/a>,3<\/a><\/sup>.<\/p>\n\n\n\n
In this article, we will understand the roles and procedures of both CRP and ESR tests. We will glean insight into how they differ, their impact on medical diagnosis and management, and the typical medical situations in which they are used.<\/p>\n\n\n\n

ESR tests alone cannot diagnose the specific condition causing inflammation; further testing is usually required. source: MedlinePlus<\/a><\/li>\n\n\n\n
ESR blood tests are non-specific and are usually used along with other tests to determine the cause or location of inflammation. source: healthdirect.gov.au<\/a><\/li>\n\n\n\n

<\/span>C-Reactive Protein (CRP) Test<\/strong><\/span><\/h2>\n\n\n\nAn important inflammation marker is the C-reactive protein or CRP 8<\/a><\/sup>. It is produced by your liver and increases during times of inflammation. A simple blood test is the usual course to measure it.\u00a0<\/p>\n\n\n\n
1. Understanding CRP and Its role<\/strong><\/h3>\n\n\n\nEssentially, CRP is an acute phase reactant. Its levels rise when the body is dealing with inflammation 1<\/a><\/sup>. This response is caused by specific proteins termed cytokines, which are produced by white blood cells in times of inflammation.<\/p>\n\n\n\n
\n
Production of CRP<\/strong><\/li>\n<\/ul>\n\n\n\nThe liver plays a central role in producing CRP. \u00a0The production of cytokines in response to inflammation stimulates the synthesis of CRP. This results in an increase in CRP levels in your bloodstream 8<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
\n
When do CRP levels increase?<\/strong>\u00a0<\/li>\n<\/ul>\n\n\n\nCRP usually spikes during bouts of inflammation. This inflammation could be triggered by an infection, injury, or any chronic inflammatory disease 4<\/a><\/sup>.<\/p>\n\n\n\n
2. CRP test procedure<\/strong><\/h3>\n\n\n\n
Measuring CRP levels requires a blood sample, which is then tested in a laboratory.<\/p>\n\n\n\n
\n
Blood sample collection<\/strong><\/li>\n<\/ul>\n\n\n\n
Blood is usually drawn from a vein. The vein is searched for on the inner side of your elbow or the back of your hand. A needle is pricked into the vein, and the blood is then collected either in an air-tight vial or a syringe.<\/p>\n\n\n\n
\n
CRP test analysis<\/strong><\/li>\n<\/ul>\n\n\n\nOnce your blood sample is collected, it is sent to a laboratory. The laboratory technicians determine CRP concentrations. This gives a clearer picture of the level of inflammation in your body 8<\/a>,9<\/a><\/sup>.\u00a0<\/p>
