A health data analyst preparing a report on PTT tests would consult which records in the health record?

The most relevant records for a health data analyst preparing a report on PTT (Partial Thromboplastin Time) tests are the clinical laboratory reports. These reports provide essential details regarding the results of the PTT tests, including the values obtained and any pertinent information about the testing methodology used. Clinical laboratory reports are specifically designed to document the results of laboratory tests and are crucial for understanding the patient's coagulation status and any related clinical implications.

While the other options might contain useful information in a broader context, they do not focus specifically on the laboratory tests. For instance, physical examination reports may provide insights into the patient's overall health but do not detail laboratory test results. Similarly, medication administration records list medications given to the patient, which might influence laboratory results but do not include the test outcomes themselves. Diagnosis reports would contain information about the conditions diagnosed but would not directly relate to the specifics of laboratory tests. Thus, the clinical laboratory reports are the appropriate records to consult for accurate and relevant data concerning PTT tests.
