🧪 Cholesterol _is a steroid with a secondary hydroxyl group in the C3 position, and found in blood, bile, and brain tissue. It serves as a precursor to
bile acids, steroids and vitamin D. It is synthesized in many types of tissue, but particularly in the liver and intestinal wall. Approximately, 75% of
cholesterol _
🔬 is newly synthesized and a 25% originates from dietary intake. Measurements of serum
⚡cholesterol levels are important in the
diagnosis and classification of hyperlipoproteinemias. Elevated cholesterol levels may occur with hypothyroidism, nephrotic syndrome, diabetes,
and various liver diseases. There is a correlation between elevated serum cholesterol levels and the incidence of coronary artery diseases.
🩺 Normal cholesterol levels are affected by stress, diet, age, gender, hormonal balance, and pregnancy. Depressed levels are associated with
hyperthyroidism and severe liver diseases1,

HBa1c vitro
Throughout the circulatory life of the red cell, Hemoglobin A1c is formed continuously by the addition of glucose to the N-terminal of the hemoglobin beta chain. This process, which is non-enzymatic, reflects the average exposure of hemoglobin to glucose over an extended period. In a classical study, Trivelli et al1 showed Hemoglobin A1c in diabetic subjects to be elevated 2-3 fold over the levels found in normal individuals. Several investigators have recommended that Hemoglobin A1c serve as an indicator of metabolic control of the diabetic, since Hemoglobin A1c levels approach normal values for diabetics in metabolic control.2,3,4
Hemoglobin A1c has been defined operationally as the “fast fraction” hemoglobins (HbA1a, A1b, A1c) that elute first during column chromatography with cation-exchange resins. The non-glycosylated hemoglobin, which consists of the bulk of the hemoglobin has been designated HbA0. The present procedure utilizes a antigen and antibody reaction to directly determine the concentration of the HbA1c.

Alkaline phosphatase refers to a group of phosphatases (pH optimum approximately 10) found in almost every tissue in the body. Most alkaline phosphatase in normal adult
serum is from the liver or biliary tract. Normal alkaline phosphatase levels are age dependent with young children and adolescents having much higher levels than adults.
Adult males tend to have higher levels than females, but pregnant females have increased levels due to placental secretion of alkaline phosphatase.2 Alkaline phosphatase
in serum consists of four structural genotypes: the liver-bone-kidney type, the intestinal type, the placental type and the variant from germ cells. It occurs in osteoblasts,
hepatocytes the kidneys, spleen, placenta, prostate, leukocytes and the small intestine. The liver-bone-kidney type is particularly important.2 Elevation of alkaline phosphatase
levels occurs in diseases such as hepatitis, cirrhosis, malignancy, chemical toxicity, and in bone diseases such as metastatic carcinoma, rickets, Paget’s disease, and
osteomalacia.3 Moderate increase in serum alkaline phosphatase levels have been observed in Hodgkin’s disease, congestive heart failure, ulcerative colitis, regional enteritis,
and intra-abdominal bacterial infections. Alkaline phosphatase levels are normally elevated during periods of active bone growth, for example, in young children and
adolescents3

Triglycerides are esters of the trihydric alcohol glycerol with 3 long chain fatty acids. They are the main lipids present in human plasma; the others are cholesterol,
phospholipids, and non-esterified fatty acids. Triglycerides are synthesized in the intestinal mucosa by the esterification of glycerol and free fatty acids. They are
then released into the mesenteric lymphatics and distributed to most tissues for storage. Triglycerides are the main storage lipids in humans, where they constitute
about 95% of adipose tissue lipids. Elevated levels of triglycerides have been associated with high risk in severe atherosclerosis. High triglycerides levels and
hyperlipidemia in general can be an inherited trait or can be secondary to disorders including diabetes mellitus, nephrosis, biliary obstruction, and metabolic
disorders associated with endocrine disturbances

Urea is the major end product of protein nitrogen metabolism. It is synthesized by the urea cycle in the liver from ammonia, which is produced by amino
acid deamination. Urea is excreted mostly by the kidneys but minimal amounts are also excreted in sweat and degraded in the intestines by bacterial
action. Determination of blood urea nitrogen is the most widely used screening test for renal function. When used in conjunction with serum creatinine
determinations it can aid in the differential diagnosis of the three types of azotemia: prerenal, renal, and postrenal. Elevations in blood urea nitrogen
concentration are seen in inadequate renal perfusion, shock, diminished blood volume (prerenal causes), chronic nephritis, nephrosclerosis, tubular
necrosis, glomerular-nephritis (renal causes), and urinary tract obstruction (postrenal causes). Transient elevations may also be seen during periods of
high protein intake. Unpredictable levels occur with liver diseases
