Laboratory testing begins with a doctor's order and is followed by specimen collection. In this activity, learners review doctors’ lab orders and select the blood collection tubes required for each patient.
Learners read about audiological tests including pure tone testing, air conduction, bone conduction, Speech Reception Threshold, and Speech Discrimination Score. They listen to sounds and words recorded at different decibel levels and see a graphic representation of decibel ranges. A brief review concludes the activity.
