| diffusion method | A method for the study of bacterial enzymes in which agar is mixed with the material (e.g., starch or milk) which is to serve as an indicator of the enzyme action and is inoculated and plated; if the bacteria produce enzymes digesting the admixed material, there will be a zone of clearing in the medium about each colony. Synonym: diffusion method. (05 Mar 2000) |
| direct method for making inlays | In dentistry, an inlay technique in which the wax pattern is made directly in the prepared cavity in the tooth. Synonym: direct technique. (05 Mar 2000) |
| disk sensitivity method | A procedure for testing the relative effectiveness of various antibiotics; small disks of paper (or other suitable material) are impregnated with known, appropriate amounts of antibiotic, and then placed on the surface of semisolid medium that has been previously inoculated with the organism being tested; after suitable periods of incubation at 37캜, the lack of growth in zones about the various disks indicates the relative effectiveness of the antibiotic. (05 Mar 2000) |
| double antibody method | A method of separating antibody-bound antigen (e.g., insulin) from free antigen by precipitating the former with antibody specific for immunoglobulin. Synonym: double antibody immunoassay, double antibody method. (05 Mar 2000) |
| double-blind method | <statistics> A method of studying a drug or procedure in which both the subjects and investigators are kept unaware of who is actually getting which specific treatment. (12 Dec 1998) |

| indicator dilution method | hamilton-Stewart method |
| Quick's method | A quantitative test for prothrombin in the blood based on the clotting time of oxalated blood plasma in the presence of thromboplastin and calcium chloride; measures the integrity of the extrinsic and common pathways of coagulation. See: prothrombin time. Synonym: Quick's method, Quick's test. (05 Mar 2000) |
