Urea is a waste product formed in liver following the breakdown of proteins. It passes into the blood, is filtered out of the kidneys and excreted in urine. Thus determination of blood urea is the […]
The O-toluidine method is an older method of blood glucose estimation. This method is no longer used today because O-toluidine is believed to be a carcinogen and is replaced by enzymatic methods. This method is […]
Most plasma proteins are too large to pass through the glomeruli of the kidney. The small amount of protein which does filter through is normally reabsorbed back into the blood by the kidney tubules. Only […]

The Arneth count is the determination of the percentage distribution of different types of neutrophils on the basis of their nuclear lobes. It is not commonly used in modern medicine. Joseph Arneth classified neutrophils into […]
The term ketone bodies refers to three intermediate products of fat metabolism, namely acetone (2%), acetoacetic acid (20%) and beta-hydroxybutyrate (78%). Under normal conditions, metabolized fats are completely broken down to water and carbon dioxide, […]
