The body’s normal temperature is around 98.6 Fahrenheit. It varies to some decimal points. For example, if it is around 97.5 or it goes up to 99, there is nothing to feel alarmed about. Low temperature may mean that you may be weak or anemic. High temperature means you have fever, and your body is responding to some illness or infection. A part of your brain called the hypothalamus controls your body temperature. When your body encounters an infection or an illness, the hypothalamus may reset the body temperature a bit higher to confuse the pathogen. Your body temperature can also be influenced by your menstrual cycle or a bout of strenuous exercise that you have just had.
The onset of fever may be accompanied by
- Sweating
- Headache
- Chills or shivering
- Loss of appetite
- Dehydration
- Excessive restlessness
If you are having these symptoms, then it is advised that you get a fever test done.

Although, fever may be a manifestation of another illness, rising temperature comes with its own problems. If the fever goes to the brain, the person can go into seizures, and this can lead to another medical problem. Hence, if one has been experiencing high temperature for a prolonged time, it is always better to get a fever test done as early as possible.
A fever test is not a single test. There may be different reasons for a high temperature, your doctor can suggest a fever test accordingly. A fever test is mostly done to find antigens or antibodies for a specific infection when you submit your blood sample. A malaria test, for example, is a category of fever test. It is a tropical disease mostly spread by mosquitoes. Another form of fever test is typhoid test. It is an illness caused by bacteria. The typhoid bacteria can enter your body through contaminated food or water. It is a serious illness and hence an immediate fever test and subsequent treatment is required. Just like malaria, dengue is another variant of a similar tropical disease spread by mosquitoes.
