Tests
A hematocrit test is a blood test that measures the amount (percent) of your blood that is made up of red blood cells. Red blood cells carry oxygen from your lungs to the rest of your body. The other parts of your blood include white blood cells (to help fight infection and other diseases), platelets (to help make blood clots to stop bleeding ), and a liquid called plasma.
Tests
A hemoglobin A1C (HbA1C) test is a blood test that shows your average level of blood glucose , also called blood sugar, over the past two to three months.
Tests
Hemoglobin electrophoresis is a test that measures the different types of hemoglobin in the blood. It also checks for hemoglobinopathy, disorders involving abnormal types of hemoglobin. Hemoglobin is a protein in your red blood cells. It carries oxygen from your lungs to the rest of your body. There are a few different types of normal and abnormal hemoglobin.
Tests
A hemoglobin test measures the levels of hemoglobin in your blood. Hemoglobin is an iron-rich protein in your red blood cells. It carries oxygen from your lungs to the rest of your body. Your cells need oxygen to grow, reproduce, and make energy for you to function. Your hemoglobin levels provide information about the health of your red blood cells. If your hemoglobin levels are abnormal, it may be a sign that you have a blood disorder .
Glossary Term
Disruption of the integrity of the erythrocyte membrane causing release of hemoglobin.
Indicators
Hepatitis A virus cellular receptor 1 (359 aa, ~39 kDa) is encoded by the human HAVCR1 gene. This protein is involved in the modulation of asthma and allergic reactions.
Tests
Hepatitis testing uses a sample of your blood to see if you have a current viral hepatitis infection or had one in the past. Hepatitis is a type of liver disease that causes liver inflammation (swelling) and damage. There are several types of hepatitis. Each affects the body and is spread in different ways.
Glossary Term
Having two different allelic forms of a gene, one inherited from each parent, on each of the two homologous chromosomes.

Glossary Term
Major protein component of chromatin. Highly conserved basic proteins, originally classified into classes based on the relative amounts of arginine and lysine in each protein. The various classes are now termed H1, H2A, H2B, H3, and H4. In chromatin, they are found in an octamer, containing two each of H2A, H2B, H3, and H4, complexed with DNA in nucleosomes. The histones in the octamer complex are also known as the core histones. The H1 class of histones, termed the linker histones, is loosely associated with the nucleosome.
Indicators
Produced by B-cells, human immunodeficiency virus (HIV) antibodies reacts with HIV antigens. HIV is a virus which affects white blood cells and eventually destroys the body's natural ability to fight infections.
