Origin of chemistry -: Chemes means black color.
Glossary of Laboratory Diagnostic Terms Accuracy Agreement between your test result value and the true value; i.
Affinity An attractive force between substances or particles that causes them to enter into and remain in chemical combination, for example; the binding of antibody to antigen. Aggregation The grouping of units or parts into a mass or whole.
Aliquot The division of a sample into at least two smaller size vials. Amplification Amplification generally means an addition to or expansion of a statement or idea.
In medical terminology, amplification refers to the selective copying of a gene or any sequence of DNA. This occurs naturally in the body in order to satisfy the increased requirement of individual cells for gene products such as proteins. Amplification also plays a role in cancer cells when a tumour cell copies DNA segments as a result of cell signals or external environmental factors.
Artificial amplification is conducted due to its central role in gene research. Analyte The chemical substance being measured in an assay, usually contained List of chemistry terms used in blood or other body fluids.
Anabolic Steroid Anabolic steroids are a group of synthetic steroid hormones that promote tissue growth and the storage of protein, as such they are sometimes used in food producing animals to increase the lean meat to fat ratio.
Treatment used to assist a primary therapy (such as surgery) in the prevention, improvement, or cure of a disease (such as adjuvant chemotherapy in cancer) Adrenal Gland One of a pair of glands located above each kidney that secretes hormones directly into the bloodstream.

Antibody A protein produced by our body in response to an antigen. The antibody binds to and neutralises the antigen. Anticoagulant A substance that stops the blood from clotting. Antigen Antigens are usually foreign substances which enter the body and trigger the immune system to produce antibodies in order to fight off the potential infection.
Antigens can be toxins, foreign blood cells, bacteria or the cells of transplanted organs. Antimicrobial The term given to a group of drugs that inhibits the growth or destroys microorganisms.
Antioxidant A molecule that protects cells from oxidative damage of oxygen and free radical molecules that are chemically unstable and cause random reactions damaging proteins nucleic acids and cell membranes. Antiserum A solution of antibody or mixture of antibodies either purified or un-purified used in the manufacture of diagnostic reagents or used as a component of a diagnostic kit.
Assay A diagnostic test to measure the concentration or level of a particular analyte.
Assayed Assayed controls are used for the control of accuracy and reproducibility of results. Assay Range The assay range describes the highest and lowest concentrations, at which a reaction is still measurable.
Aspiration The withdrawal of fluid or tissue, e. Aqueous The term aqueous simply means dissolved in water. Avidity The average affinity of a mixture of antibody to their corresponding antigen. B Benchtop This term simply refers to a position of an object, i.
However, in a scientific setting, it is used to describe an analyser which is small enough to fit on top of a laboratory workbench but is too large to be a point of care system.
Bias The term bias refers to the difference between the expected result and an accepted reference value. Biochemistry Biochemistry is the study of the chemical structures and vital processes which occur in living organisms.
Biochemists study the compounds in the body and how these result in chemical processes. They seek to understand such processes both within healthy and unhealthy organisms.
Biochip Proprietary solid substrate onto which reactive species are prefabricated for the detection of specific analytes. Individual homeostatic setting points usually vary. This difference is known as biological variation.
Biotechnology As the name suggests, this field of study is a combination of biology and technology. It is primarily concerned with the technical exploitation of biological processes. Through microbiological or biochemical techniques, cell cultures, microorganisms or enzymes are used to activate targeted metabolic processes.
Used in conjunction with genetic engineering, biotechnology can be used to program certain microorganisms to perform specific tasks. Blood Clotting Blood clotting, also known as coagulation performs the vital task of preventing excessive blood loss in the event of injury. Leakage of blood is prevented by the blood cells sticking to the wound.
However, clotting can sometimes fail to occur, this is known as haemophilia. Blood Gas Analysis The body has many functions, one critical function is to transport substances such as oxygen, carbon dioxide, nutrients and excretions.
Most of these substances are gases; therefore blood gas analysis determines their concentrations in arterial and venous blood.Chemistry Vocabulary Words. From the textbook Physical Science, (Glencoe Science made) Chapters excluding For finals.
