The meaning and the normal range of blood test indicators

Total Protein
This is a measure of the total amount of protein in your blood. Total protein is the combination of albumin and total globulin and is affected by the albumin and total globulin. A low or high total protein does not indicate a specific disease, but it does indicate that some additional tests may be required to determine if there is a problem.
Clinical Adult Range : 6.0 g/dL - 8.5 g/dL 

Iron
The body must have iron to make hemoglobin and to help transfer oxygen to the muscle. If the body is low in iron, all body cells, particularly muscles in adults and brain cells in children, do not function up to par. If this test is low you should consider getting a Ferritin test, especially if you are female who still has menstrual cycles.
Clinical Adult Range : 40 ug/ml - 150 ug/ml

Ferritin
This test is considered the "gold standard" in documenting iron deficiency anemia. Low levels below 25 indicate a need for iron. High levels ma an inflammatory disorder, infections, rheumatoid arthritis, chronic kidney disease.
Clinical Female Adult Range (after menopause) : 12 ng/mL - 263 ng/mL

Triglycerides
These are fats used as fuel by the body, and as an energy source for metabolism. Increased levels are almost always a sign of too much carbohydrate intake and hyperlipidiam. Decreased levels are seen in hyperthyroidism, malnutrition and malabsorption.
Clinical Adult Range : 50 mg/dL - 150 mg/dL

Cholesterol
Group of fats vital to cell membranes, nerve fibers and bile salts, and a necessary precursor for the sex hormones. High levels indicate diet high in carbohydrates / sugars. Low levels indicate low fat diet, malabsorption, anemia, liver disorders, carbohydrate sensitivity. Cholesterol values below 140 are considered one of the four OMINOUS signs.
Clinical Adult Range : 120 mg/dL - 200 mg/dL

LDL Cholesterol
LDL is the cholesterol rich remnants of the lipid transport vehicle VLDL (very-low density lipoproteins) there have been many studies to correlate the association between high levels of LDL and arterial arteriosclerosis.
Clinical Adult Range : 130 mg/dL

HDL
HDL or High-density lipoprotein is the cholesterol carried by the alpha lipoproteins. A high level of HDL is an indication of a healthy metabolic system if there is no sign of liver disease or intoxication. The two mechanisms that explain how HDL offers protection against chronic heart disease are that HDL inhibits cellular uptake of LDL and serves as a carrier that removes cholesterol from the peripheral tissues and transports it back to the liver for catabolism.
Clinical Adult Female Range : 60 mg/dL 

Cholesteral / HDL Ratio
This ratio is an important marker for cardiovascular health. A ration Lessthan 4.0 is considered adequate. A ration Lessthan 3.1 is ideal.
