Step-by-step explanation:
The first step in the testing process begins when the D) test is ordered by the healthcare provider. This order usually comes after a physical examination or discussion of symptoms with a patient. Once the test is ordered, a specimen is collected from the patient and is carefully labelled with the patient's details. This specimen, which can be any biological sample like blood, urine etc., is then delivered to the laboratory. In the lab, a laboratory technician receives the sample. If we take a blood sample for example, it may be left in a glass tube for a certain period for coagulation. Afterwards, serum is separated for analysis. If the sample was blood, it could be tested for things like blood type. For instance, if anti-A and anti-B antibodies were added to the sample and both wells agglutinated, it would indicate that the patient has AB blood type.
