A small needle attached to a collection vial will be inserted into a vein and a small amount of blood will be withdrawn. When the vial is full, the needle and strap will be removed and a cotton ball will be taped over the injection site.
The blood specimen for a CRP test is usually collected in a lavender-top or clear tube with an EDTA anticoagulant. This tube is also sometimes referred to as a "purple-top" tube.
No advance preparation for the CRP test is needed on the part of the patient. The test is conducted on a small sample of blood that usually takes about a minute to withdraw from a patient's vein.
A lavender-top tube is typically used for collecting samples for C-reactive protein (CRP) testing.
CRP HS is not a blood disorder; it's a chemical in the blood (C reactive protein).
When performing a CRP (C-reactive protein) test, blood is typically mixed with a reagent that recognizes CRP and causes a visible reaction, such as a change in color. This reaction helps to quantify the level of CRP present in the blood, which can indicate inflammation or infection in the body.
The CRP test is performed in a laboratory and the results are usually available in three to five days.
The recommended tube for C Reactive Protein (CRP) testing is a serum separator tube (SST) with a red or gold stopper. This allows for the separation of serum from the blood cells, which is required for accurate CRP measurements.

Typically, a lavender or blue-top tube is used to collect samples for CRP (C-reactive protein) testing.
Your blood will undergo rigorous testing procedures. In addition to blood typing, the tests include screening for hepatitis, syphilis, and HIV
red or gold
A C-reactive protein (CRP) blood test measures the level of CRP in the bloodstream, which is a marker of inflammation in the body. Elevated CRP levels can indicate an underlying infection or inflammatory condition, and the test is often used to assess the risk of heart disease or monitor response to treatment.
