by

Introduction Perl’s staining, also known as Prussian blue staining, is a specialized histochemical technique widely used in histopathology to detect the presence of iron in biological tissues. This method is particularly valuable in diagnosing various diseases related to iron metabolism, such as hemochromatosis and hemosiderosis. The staining highlights iron deposits, allowing pathologists to visualize and … Read more

zinc testing, plasma zinc test

by

Zinc is an essential trace mineral, meaning that the body needs it in small amounts but cannot produce it on its own. It plays a pivotal role in numerous biological processes, acting as a cofactor for over 300 enzymes involved in various functions such as metabolism, immune function, DNA synthesis, and wound healing. Additionally, zinc … Read more

C-peptide testing

by

What is C-peptide? C peptide originates in pancreatic beta cells as a byproduct of enzymatic cleavage of pro-insulin to insulin .C-peptide is a connecting peptide that gets released alongside insulin from the pancreas. While insulin helps usher glucose (sugar) from the bloodstream into cells for energy, C-peptide itself has no known function in the body. … Read more
