In screening, two tests are often necessary each with different performance characteristics. These may be offered at the same time (parallel testing) or sequentially (serial testing) [1].
Parallel versus serial testing.
| Testing strategy: | Parallel testing | Serial testing |
|---|---|---|
| Procedure: | Two screening tests performed at the same time and the results are subsequently combined | Second screening test is performed only if the result of the first screening test is positive |
| Effect: | Higher sensitivity but lower specificity | Improves specificity at the cost of lower sensitivity |
