 ### Use Case 3: Requesting additional examinations of the same sample
 
 It is not uncommon for the results of laboratory tests to lead to the request for additional tests on the same sample. In the example 1-tvt, venous thrombophilia may be suspected, so that further laboratory tests can detect hereditary causes such as factor V Leiden mutation, prothrombin gene mutation, antithrombin deficiency, etc.

 After the laboratory order has been received and processed, the situation may arise in which the laboratory physician wishes to make suggestions for additional or alternative examinations to the author of the order. He can use the received order document for this purpose, exchange the personal data of the sender and receiver through his information system, and send it back with the suggestions for further or alternative laboratory examinations.

 If this is of particular interest for the interpretation of the prescribed examination, it must be possible to include further data on the patient's state of health in the laboratory order. These are existing findings, medical reports and documents.

 For certain tests, the order and sample alone are not sufficient to determine the laboratory result. In such cases, observations on the sample collection must be supplied to the laboratory. An example of this is the determination of creatinine clearance in 24 h urine. For this purpose, the laboratory must know the amount of urine collected during a certain period of time. Therefore the ordering party provides the laboratory with the urine volume, as well as a sample of the urine and serum.

 Another example is the Synacthen(ACTH) function test, where a basal Blood sample is collected in the morning fasting, followed immediately by the Synacthen injection, and a second Blood sample is collected an hour later.
