Clinical pathology tests analyze bodily fluids (like blood, urine, or cerebrospinal fluid) and tissues to diagnose, monitor, and treat diseases. Common tests include:
These tests play a vital role in providing accurate, early diagnoses and guiding effective treatment plans.
We will learn about “What is ggt in a blood test?”. GGT (Gamma-glutamyl transpeptidase) is an enzyme that is primarily found in the liver and bile ducts. It plays a role in the metabolism of glutathione. Elevated levels of GGT in the blood can indicate liver or bile duct damage or disease, such as liver … Read more
Water deprivation test used to differentiate the causes between diabetes insipidus and primary polydipsia. Water deprivation test principle The period after the administration of the desmopressin tests for the kidney’s ability to vasopressin and therefore differentiates between cranial and nephrogenic Diabetes Insipidus. The results of this test may be equivocal, necessitating further investigation. Water deprivation … Read more
Benedict’s test is a simple chemical that can be used to assess the presence of reducing sugars. Reducing sugars have free aldose or ketose groups, which are capable of donating electrons to other molecules by oxidizing them. Reducing sugars are mostly monosaccharides (e.g. glucose, fructose, galactose) and some of them are disaccharides which are lactose … Read more
Serum amylase test is important for calculation of hydrolytic enzyme which hydrolyses starch into maltose. It present in saliva and pancreatic juice where it is secreted by parotid glands and pancreas respectively. Small amounts of leak into circulation due to where and tear of cells in these glands. The circulating enzyme is excreted by the … Read more
The Schick test is a diagnostic tool used to determine an individual’s immune status against diphtheria toxin. Schick test principle The test involves injecting a small amount of inactivated diphtheria toxin just below the surface of the skin, usually on the forearm. If the individual has sufficient levels of antibodies against the toxin, there will … Read more
Hyperlipidemia means a high level of lipid content in the blood. It may be due to a primary cause or secondary. Secondary cause due to some kinds of disease Fredrickson classified hyperlipidemia on the base of an electrophoretic pattern of lipoprotein. There are six types of hyperlipidemia. Here’s the video of Fredrickson’s classification of hyperlipidemia … Read more
Human blood consists of blood cells (red blood cells, white blood cells, and platelets) and electrolytes (sodium, potassium, and calcium ions). Some diseases change electrolytes concentration like Cushing disease cause hypernatremia while Addison disease causes hyponatremia. Some diseases alter the potassium level and cause hyponatremia or hypernatremia. Hyperkalemia and hypokalemia are two opposite conditions related … Read more
Hypernatremia and hyponatremia are two different medical terms. Hypernatremia medical definition is “Hyper means “excess” while hypo means “low”. Hypernatremia condition occurs when sodium ions concentration is increased by any cause. In the same way, when Na+ concentration is less than normal. It is known as hyponatremia. There are two types of electrolytes in our … Read more
Ion-selective electrode (ISE) is an important instrument for analyzing various electrolytes like Sodium, Potassium, Chloride, and Lithium in the pathology laboratory. ISE is used in many departments of the medical field. Principle of the ion selective electrode (ISE) ISE principle is that, it create potential that is proportional to the concentration of the tested analyte. … Read more
The estimated Glomerular filtration rate (eGRT) blood test is an important and essential test for assessing the filtration ability of both kidneys. egfr-stands for “Estimated glomerular filtration rate” In the case of chronic kidney disease (CKD) eGFR decreases. what is the glomerular filtration rate? An estimated glomerular filtration rate test is used to measure the … Read more
