A basic diagnostic laboratory package for assessing serum proteins. This includes measuring total protein, which provides an overview of the balance between protein synthesis and loss in the body. This measurement is then broken down into its two main components: albumin, the most abundant protein produced by the liver and which plays a crucial role in maintaining vascular osmotic pressure, and globulin, a term encompassing a broad group of proteins including antibodies and acute-phase proteins. The albumin-to-globulin ratio (A/G ratio) is calculated, providing valuable diagnostic information.
