Several antibody tests can equal the performance of EIA and do not need special equipment or highly trained staff. These tests are considered rapid if they take less than 10 minutes and simple if they take longer.There are four types of assay: agglutination, comb/dipstick, flow-through membrane and lateral flow membrane. In most formats, the appearance of a clearly visible dot or line indicates a positive result. Many of the tests have an internal control sample, which validates each test run. Test kits are relatively expensive at US$ 1-2 per test.
