- two-pronged, forklike instrument that vibrates when struck; used to test hearing, especially bone conduction; most commonly used is "C" 1024 Hz (same level as normal speech)
- instrument used for visual examination of the ear; An otoscope is an instrument which is used to look into the ear canal. The ear speculum (a cone-shaped viewing piece of the otoscope) is slowly inserted into the ear canal while looking into the otoscope. The speculum is angled slightly toward the person's nose to follow the canal. A light beam extends beyond the viewing tip of the speculum. The otoscope is gently moved to different angles to view the canal walls and eardrum.

- HgB Test measures concentration of the hemoglobin in the blood. Hemoglobin levels are a rough measure of the oxygen-carrying capacity of the blood. Normal ranges: W:12-16 g/dL; M:15-17 g/dL Anemia is detected with Hgb measurement
- The basal state is the patient's state in early morning, about 12 hours after the last meal. Best blood samples are collected at this time.

If they did eat but Dr. still wants test, write "non-fasting" on lab requisition.
