Indirect memory tests assess the retention of information without direct reference to the source of information. Participants are given tasks designed to elicit knowledge that was acquired incidentally or unconsciously and is evident when performance shows greater inclination towards items initially presented than new items.

The direct and indirect Coombs tests, also known as antiglobulin test (AGT), are blood tests used in immunohematology. The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells. [1] Since these antibodies sometimes destroy red blood cells they can cause anemia; this test can help clarify the condition.
Photomicrograph of a histological section of human skin prepared for direct immunofluorescence using an anti-IgG antibody. The skin is from a patient with systemic lupus erythematosus and shows IgG deposit at two different places: The first is a band-like deposit along the epidermal basement membrane ("lupus band test" is positive).
Direct assay In a direct assay, the stimulus applied to the subject is specific and directly measurable, and the response to that stimulus is recorded. The variable of interest is the specific stimulus required to produce a response of interest (ex. death of the subject). [6] [12] Indirect assay
For example, if a test sample returns an OD of 1.0, the point on the standard curve that gave OD = 1.0 must be of the same analyte concentration as the sample. [citation needed] The use and meaning of the names "indirect ELISA" and "direct ELISA" differs in the literature and on web sites depending on the context of the experiment.
A 2022 analysis did an adjusted indirect treatment comparison (meaning the medications’ effects from other studies were compared rather than testing both in one study). ... a direct comparison ...
There are two main types of antiglobulin testing: indirect and direct. [17] [18] Indirect antiglobulin testing is used to detect antibodies in plasma/serum, whereas direct antiglobulin testing is used to detect antibody bound to red blood cells. When the direct antiglobulin test is positive, we must perform an antibody elution to remove the ...
The income tax is a direct tax, so it’s obvious — but you fund your government all year long through the slow, steady drip of indirect taxes, too. Learn: How To Itemize Deductions Like a Tax Pro
