Testing
The "Multitest Mérieux" or "CMI Multitest" system (Multitest IMC, Istituto Merieux Italia, Rome, Italy) has been used as a general test of the level of cellular immunity. It is an intradermal test of skin reactivity (similar to tuberculin tests) in which a control (glycerol) is used with seven antigens of bacterial or fungal origin (tetanus toxoid, tuberculin, diphtheria, streptococcus, candida, trichophyton, and proteus). In this test reactions are categorized according to the number of antigens provoking a response and the summed extent of the skin response to all seven antigens. Here anergy is defined as a region of skin reactivity of 0-1 mm, hypoergy as a reaction of 2–9 mm in response to fewer than three antigens, normoergy as a reaction of 10–39 mm or to three or more antigens, and hyperergy for a reaction of 40 mm or more.

Famous quotes containing the word testing:
“Traditional scientific method has always been at the very best 20-20 hindsight. It’s good for seeing where you’ve been. It’s good for testing the truth of what you think you know, but it can’t tell you where you ought to go.”
—Robert M. Pirsig (b. 1928)
“Now I see that going out into the testing ground of men it is the tongue and not the deed that wins the day.”
—Sophocles (497–406/5 B.C.)
“No testing has overtaken you that is not common to everyone. God is faithful, and he will not let you be tested beyond your strength, but with the testing he will also provide the way out so that you may be able to endure it.”
—Bible: New Testament, 1 Corinthians 10:13.
