Answer:
O4) Screening tests
Step-by-step explanation:
The screening test is used to make early detection of diseases in order to apply effective treatments. For example, a screening blood test enables the identification of toxins and/or drugs in the patient's system in a relatively low amount of time (generally 24 hours). This bioassay is used for the toxin determination of the effluent sample (i.e., a sample collected and analyzed to evaluate system performance) to the tested species. The screening test generally consists of applying two treatments (i.e., one effluent sample and one control).
