2. to induce such propagation.
3. the product of such propagation.
4. the shared values, beliefs, and practices of a particular group of people, which are transmitted from one generation to the next and are identified as patterns that guide the thinking and action of the group members. adj., adj cul´tural.
cell culture the maintenance or growth of animal cells in vitro, or a culture of such cells.
blood culture microbiologic examination of a blood sample to check for presence of microorganisms.
continuous flow culture the cultivation of bacteria in a continuous flow of fresh medium to maintain bacterial growth in logarithmic phase.

HIV test

Various tests have been used to detect HIV and production of antibodies thereto; some HTs shown below are no longer actively used, but are listed for completeness and context. See HIV, Immunoblot.
HIV tests
Culture The direct culture of HIV in the appropriate cell–human lymphocytes
IgA assay An immunoblot-type assay which allows the early diagnosis in infants of perinatal HIV infection
p24 antigen The measurement of HIV's p24 antigen by immunoassay, confirmation by neutralization; very low sensitivity
PCR Amplification of HIV nucleotide sequences by PCR, used to confirm indeterminate Western blot results
