Hcb meaning in blood test

A high hemoglobin count indicates an above-normal level of the iron-containing protein in red blood cells. Hemoglobin often abbreviated as Hb or Hgb is the oxygen-carrying component of red blood cells.

Most people who get infected with hepatitis C virus HCV develop a chronic, or lifelong, infection. Left untreated, chronic hepatitis C can cause serious health problems, including liver damage, cirrhosis, liver cancer, and even death. People can live without symptoms or feeling sick, so testing is the only way to know if you have hepatitis C. Getting tested is important to find out if you are infected so you can get lifesaving treatment that can cure hepatitis C. A blood test, called an HCV antibody test, is used to find out if someone has ever been infected with the hepatitis C virus.

They are suspected to induce immunologic impairments in exposed individuals. We examined dose-response relationships of blood levels of these chemicals with cellular numbers of lymphocyte subpopulations, in vitro lymphocyte response or humoral plasma cytokine levels, immunoglobulin autoantibodies immunologic dysfunctions. We studied patients who had been occupationally exposed primarily to PCBs for more than 6 months. Lymphocyte subpopulations, in vitro responses to mitogens and allogeneic stimulator cells, plasma neopterin, cytokines, soluble cytokine receptors, soluble adhesion molecules, anti-Ig autoantibodies, and liver transaminases were determined. Blood levels of the different compounds were strongly correlated with one another.

A hemoglobin test measures the amount of hemoglobin in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs.
