Blood test of lactic acidosis

Lactic acidosis is caused by high levels of lactic acid (lactate) and protons in the bodily secretions and is usually associated with poor clinical outcomes. The intensity and clinical setting of lactic acidosis influence its impact. Lactic acid, a carbohydrate metabolism intermediate, is mostly produced by white skeletal muscle, the …

Understanding Atherosclerosis: Causes, Risks, and Management

Atherosclerosis, also known as coronary artery disease (CAD), is the most common form of cardiovascular disease (CVD) and a leading cause of death worldwide. This condition is characterized by the buildup of lipids (fats) and inflammation in the large arteries. Over time, this accumulation can lead to severe complications like …

LDL Cholesterol calculation equations

Low-density lipoprotein cholesterol, or LDL cholesterol, is a kind of fat that circulates in the blood, transporting cholesterol across the body to where it’s needed for cell repair and depositing it inside artery walls. Because cholesterol and triglycerides are water insoluble, they must be bound to proteins in order to …

Types of Laboratory grade water

Water quality is considered by many laboratorians to be one of the most important preanalytical variables that impacts laboratory testing. Many people believe water to be a laboratory reagent, and it’s used to make buffers, blanks, calibrators, controls, mobile phase, reaction mixtures, and reagent reconstitution for a variety of lab …

Acid base balances and Arterial blood gas

Different kinds of biological fluids exist within the human body. These can be found in the intracellular and extracellular fluid compartments, respectively. Plasma is stored in the vascular compartment. Interstitial (including lymphatic), cerebral, pleural, pericardial, and gastrointestinal fluids are all included in the extravascular compartment. All body fluids have critical …

Factors interfering analytic tests

As a result of interfering factors, test results might be affected. When it comes to interference factors, it relies on the method adopted to analyze the same analyte. Hemolysis, lipemia, icterus, drugs, paraproteins, and other sample contaminants, such as gels, tube additives, and fibrin clots, are all examples of interference …

Hypocalcemia and Hypercalcemia

Calcium is required for efficient cellular function and signaling, as well as neuromuscular transmission, cardiac contractility, hormone secretion, and blood coagulation. Extracellular calcium concentrations are controlled within an extremely narrow range thanks to a number of feedback processes including parathyroid hormone (PTH) and the active vitamin D metabolite 1,25-dihydroxyvitmin D …

Prostate specific antigen (PSA)

PSA is a protein released by the prostate gland. PSA is a kallikrein-family serine protease that has been commonly used to screen men for prostate cancer. It’s also used to monitor recurrence and therapy response after initial treatment. PSA is developed in both normal and cancerous prostate tissue. PSA is …

Measurement of Urine and Plasma Osmolality

Osmometry is a method of determining the concentration of solute particles in a solution that add to the osmotic pressure. The flow of a solvent (in biological systems, water) through membranes that separate two solutions is regulated by osmotic pressure. The ability to choose molecules of various sizes and shapes …
