Grants, Contracts, RFAs, and RFPs. 1  A grant is a funding mechanism for a particular scientific inquiry that you generate. You come up with the idea, they decide if it's a good idea, and they provide funding for you to do it. In contrast, a contract is a funding mechanism of government agencies or other organizations to obtain specified services or goods.
1 Chlamydia culture. 2  This is a test to find the bacteria that cause a chlamydia infection. 3  A sample of body fluid from areas such as the cervix, urethra, eye, rectum, or throat is added to certain cells used to grow chlamydia.
Chlamydia and gonorrhea tests detect the actual bacteria in the sample. Some tests use a urine sample or cervical swab. If the test is positive, the person has a current STD infection that requires treatment. The syphilis test is a blood test. It detects an antibody produced by the body in response to the infection. The test does not distinguish between a current or past infection and, if it is positive, confirmatory testing will be required.
