Final answer:
The laboratory request form is used to record laboratory data collected from an animal, not to be confused with treatment sheets, prescription forms, or pathology reports.
Step-by-step explanation:
The form used for recording the laboratory data collected from an animal is a laboratory request form. This form is essential when submitting samples for laboratory analysis and once the data is collected, it helps in documenting the results obtained. The laboratory request form typically includes information such as the animal's identification, the test(s) requested, the reason for the test, and the date the sample was taken. The other forms listed have different purposes: a treatment sheet is for recording medications and treatments administered, a prescription form is for ordering medication, and a pathology report is an analysis of the test results by a pathologist.
