While it can seem scary for your doctor to order blood work, there are actually several common reasons for lab work to be done. Whether it’s to determine the cause of fatigue or to get a more complete view of your health, doctors order blood work on a daily basis. The following are just five common reasons your doctor will order blood work.
Those suffering from fatigue may have a number of medical conditions. While fatigue can be caused by something as simple as poor sleeping or eating habits, there can be a more serious condition causing the problem. Doctors will often order a complete blood count to determine whether or not there is a problem with your blood count.
If you’re experiencing the signs of diabetes, a doctor will order a glucose test to be preformed. Many glucose tests are done in the office and require only a prick of the finger. Other glucose tests may require more blood to get a more accurate and lengthier view of your levels. Either way, a fast is usually required before the test is done.
Another common aliment that doctors routinely check for is high cholesterol. A doctor may run a test to check your lipoprotein levels which will give an accurate view of your good and bad levels of cholesterol. High cholesterol does not come with any symptoms and this test is necessary to determine whether or not your numbers are in line.
Complete Blood Count
A complete blood count is done to check for a variety of illnesses. Those complaining of fatigue, weakness or even depression may be asked to have a complete blood count preformed. The count gives a view of how many white and red blood cells are in the blood along with the number of platelets. These numbers are used to determine whether or not you suffer from anemia, kidney disease and other disorders.
Last, but certainly not least, many doctors order blood work not because it is necessary, but because your insurance will pay for it. The problem is when you really do need blood work done, you may be charged for it. Always ask why the doctor is ordering the blood work and if he doesn’t have a good answer, don’t get it done.
There are a number of reasons why blood work is needed by your doctor. Unfortunately, many doctors also put in requests simply because you have a good insurance plan. Be weary of doctors that order blood work too often, especially when you’re only there for a routine checkup.
