No, the laboratory thermometer can not be used to measure the temperature of a human body as range of thermometer is high.
- The standard human body temperature is 37°C while laboratory thermometer temperature range is from -10°C to 110°C which is high
- A clinical thermometer is suitable to measure the temperature of humans as it has a range from 35 C to 42°C.
- Moreover, if you use the lab thermometer and the bulb is taken out of the mouth, the mercury starts falling.

Answer:
A laboratory thermometer cannot be used to measure the human body temperature. This is because as soon as we take out the bulb of the laboratory thermometer from our mouth, the level of mercury in its tube will start falling quickly. This will give a wrong value of the body temperature.
