What Is A Blood Test And What Are The Necessities For Performing This Test In Blood Test Labs
Blood test can be defined as a test being conducted on a sample of blood in a laboratory by either a doctor, nurse or lab technician. The blood sample is extracted either by a finger pick using a sterile needle or from an arm vein. Even though this examination on blood is called as blood tests, usually the tests are being done only using the blood plasma and only the haematology tests are being performed using the blood and as well as the blood plasma. The main target for performing a blood test is to study about the biochemical and physiological levels of a person. This allows detecting the presence or absence of a disease, the patient’s mineral level, to predict the effect of a particular drug, the functions of a person organs etc. Blood tests are basis for most of the disease analyses and also for drug tests. Most of the blood tests requires sample from the models vein. But some other blood tests including some special studies would require blood extraction from an artery of the patient.
A typical example for these special studies includes arterial blood gas. Using the blood sample from an artery it is possible to detect the levels of carbon dioxide and oxygen of the patient in order to study their pulmonary function. It is also possible to determine the blood pH and levels of bicarbonate in the blood sample from an artery which helps to predict some metabolic conditions in the patients. Earlier times blood tests were only performed in the Blood Test Labs located inside the hospitals. But due to the large number of demands from the public, there are a number of private Blood Test Lab Locations launched all over the cities worldwide. By the help of these private Blood Test Labs the common people are able to detect the normal range of their blood without any doctor’s advice.
