Understanding and Significance of Blood Testing
Last Edited: July 5th, 2012
A blood test is an essential laboratory process that can verify an individual’s physiological and biochemical state from the time a child is bear, this process may by now be necessary or ordered by doctors. Medical technologists carry out this laboratory study on a blood example. The blood is usually taken out from an individual’s major vein located just below the midpoint of the right arm.

Distinctively, a blood examination will be able to verify if an individual bear definite virus or disease and whether his inner organs are working well or not. It can also detect the mineral substance in the body, the efficiency of medicines and even whether a woman is pregnant.

On the whole, there are three types of blood analysis and these are the biochemical analysis, molecular profiles and cellular evaluation.

Biochemical analysis – This blood examination deals the level of an individual’s sodium, potassium, chloride, bicarbonate, magnesium, calcium, creatinine, glucose and blood urea nitrogen. Before having your blood test taken at the laboratory, patients are typically asked to fast or not eat anything eight to 12 hours. This is a must for people wanting to check their blood sugar and cholesterol levels.

All the way through this assessment, doctors are then able to recommend what types of foodstuff their patients need to stay away  to keep being healthy.

Molecular profiling – This type of examination permits medical experts to verify the molecular anatomy of body cells mainly related to illnesses. This also support them expand new analytical and therapeutic methods for clinical involvement. Particularly, this blood examination looks into and organizes tissues to be able to deliver an exact diagnosis and prognosis on the patient’s state.

Molecular profiles differ and these consist of protein electrophoresis, the western blot (identify the occurrence of antibodies particularly antibodies), liver function test (aim the blood levels in the liver), polymerase chain reaction (focuses on the DNA sequences), northern blot (focuses on RNA sequences) and sexually transmitted disease or STD.

Cellular evaluation – This examination wraps dissimilar types such as the full blood count, cross matching and blood cultures. The full blood count is a practice test vital to find out a patient’s WBC count, RBC count, hematocrit, hemoglobin and red cell supply (erythrocyte sedimentation rate). This is useful in identifying the stage of an individual’s disease.

Cross matching is the procedure required before a blood transfusion performs. It aims to test the blood compatibility of the donor and the potential recipient. This process can be completed throughout the computer or serologically by a qualified laboratory technician.

Blood cultures are destined to verify the occurrence of microorganisms plus bacteria and fungi in the blood. The blood sample is nurtured in a controlled environment and then observed for microorganisms. Up to three blood cultures need to be done to be able to verify whether the result is positive or negative.

A plain blood analysis does not create any danger or risk so this is supposed to be not scare you if you’re being asked by your doctor to take one. Slight difficulty may happen but these are only in rare cases. Possible complications consist of infection, bleeding, bruising, dizziness and hematoma.
