Hcb meaning in blood test

A high hemoglobin count indicates an above-normal level of the iron-containing protein in red blood cells.

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. To assess possible cumulative effects, we compared patients who had blood levels of all compounds below background with patients who had blood levels of all compounds above background. Patients with low or absent blood levels of the compounds studied had higher IFN-[gamma] plasma levels, providing some evidence for a cumulative effect of several weakly active compounds.

This test looks for antibodies called IgM in your blood. The test is used to find out whether you are actively infected with the hepatitis B virus HBV. HBV has a central core and a surrounding envelope. People who have had the hepatitis B vaccine will not have the core antibody in their blood. HBV is 1 of 5 hepatitis viruses. The others are hepatitis A, C, D, and E. Most hepatitis infections are caused by these 5 viruses. HBV is spread through blood, seminal fluid, and vaginal secretions. It can take 60 to days to develop symptoms of hepatitis B after you become infected. The virus causes an infection in the liver. In most cases, this virus clears up on its own within 6 months.

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. Antibodies are chemicals released into the bloodstream when someone gets infected.

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. If a hemoglobin test reveals that your hemoglobin level is lower than normal, it means you have a low red blood cell count anemia. Anemia can have many different causes, including vitamin deficiencies, bleeding and chronic diseases. If a hemoglobin test shows a higher than normal level, there are several potential causes — the blood disorder polycythemia vera, living at a high altitude, smoking and dehydration.

The human chorionic gonadotropin hCG blood test measures the level of hCG hormone present in a sample of your blood. Human chorionic gonadotropin hCG is produced during pregnancy. Your doctor may refer to the hCG blood test by another name, such as the:. There are important differences between hCG blood tests and the hCG urine tests that you can purchase over the counter. Urine tests can be influenced by factors such as dehydration and the time of day that you test, while an hCG blood test can provide conclusive results even in cases where hCG levels are quite low.
