LiquiCHECK Flashcards
is a major carbohydrate present in the blood & serves as a primary source of energy.
It is usually obtained from ingested starch & sugar.
Glucose
Excessive glucose is stored as inactive_____ mainly in the liver & little in the muscles.
glycogen
Elevated blood glucose levels are found in
diabetes mellitus
hyperthyroidism
hyperadrenalism
certain liver diseases
Decreased glucose levels are found in
Insulinoma
hypothyroidism
hypopituitarism

Glucose Calculation
Glucose Concentration (mg/dL) =
Absorbance of sample/ Absorbance of standard
x standard conc.
Linearity
This reagent is linear upto 600 mg/dL.
If the concentration is greater than linearity (600 mg/dL)dilute the sample with normal saline and repeat the assay
Glucose
are simple lipids, formed in the liver by glycerol & fatty acids.
Triglycerides
are transported by VLDL, LDL & constitute about 95% of fat, stored as source of energy in the tissue & plasma
Triglycerides
Increased levels are found in hyperlipidemias, diabetes, nephrotic syndrome & hypothyroidism.
Increased levels are risk factor for arteriosclerotic coronary disease, peripheral vascular disease, acute pancreatitis & hyperlipoproteinaemia

It is the main lipid found in the blood, bile & brain tissues
Cholesterol
It is also one of the most important steroids of the body & is a precursor of many steroid hormones.
Cholesterol
Increased levels are found in hypercholesterolaemia, hyperlipidaemia, hypothyroidism, uncontrolled diabetes, nephritic syndrome & cirrhosis.
Decreased levels are found in malabsorption, malnutrition, hyperthyroidism, anaemia & liver diseases.
