Importance of Biochemical Blood Analysis

The bio-chemical blood analysis is a laboratory method of study which is used in all departments of medicine. It correlates body functions and conditions and helps in identifying and addressing the root cause of the problem rather than chasing symptoms or simply guessing. The blood sample for biochemical analysis is taken on an empty stomach, after a 12 hour fasting.

Biochemical testing is generally carried out on the watery portion of the blood (serum or plasma) as opposed to the Full Blood Count test.   It includes an in-depth analysis of the balance and influence of one organ on the other, which foods suit a particular metabolic type and what are the kinds of supplementary foods one should take to bring the imbalance under control.

The blood analysis includes the determination of serum, bilirubin, iron, potassium, calcium, sodium, creatine, KFK etc. Blood sample for such tests is taken from the vein. There are many substances which are analyzed in this test but the most common ones are:

Electrolytes
which include sodium, potassium and chloride are important in maintaining fluid balance across cell membranes. The change in levels can give indication about dehydration and kidney functions.

Calcium
is significant for cell membrane function and bone formation. Abnormality in the calcium level can lead to kidney dysfunction, thyroid gland and mal-absorption problem in gastrointestinal tracts.

Urea
also known as blood urea nitrogen is a waste product from the protein metabolism and can be tested for the kidney efficiency.

Glucose
is the sugar that provides energy to the body. It is tested to diagnose and monitor diabetes.

Liver Enzymes
are tested for damages or infection to the liver which is responsible for a lot many chemical processes in the body.

Cholesterol levels are linked to heart disease and these tests are done to determine their levels in the human body.
