Doctors order lab tests for a variety of reasons, but the basis behind all of them is to obtain information that will allow for more accurate diagnoses and treatment options. Your doctor may order tests that require a sample of your blood, urine, or tissues, which are then sent to the appropriate laboratory for testing. There are many different kinds of tests for each sample, and your doctor will choose the ones that will provide the information needed to address your current health concerns.
How Lab Tests Help
Doctors use lab tests in many different ways, including:
>> Diagnosis of a suspected illness or disease
>> Identification of changes in your health that may occur without symptoms
>> Developing treatment options for your specific health issue
>> Monitoring of a disease or illness
>> Evaluation of whether your body is responding to current treatments
All of these uses are an important part of managing your health, and they provide valuable information the doctor can use to determine the best methods of treating your illness.
Once the required samples have been collected, they will be sent to the appropriate lab for testing. The analysis process can include the introduction of different substances to your sample to see whether there is any reaction. If your sample does react with any of the substances introduced, it allows the technician to determine whether you do or do not have a specific condition or disorder.
Lab testing is also used to keep track of any changes that may be taking place in your body. In these cases, the new sample will be compared with any previous samples to determine if there are any changes taking place. The results of this comparison will allow your doctor to determine whether your treatment should remain the same, or be altered for better results.
Once the analysis is complete, the results are generally labeled with a given range. These ranges are used as a determining factor between normal results, and those that indicate a problem is present. These ranges often vary considerably, and can change from one person to the next.
While some lab results provide the information needed for an exact diagnosis, others may only provide general information. Your doctor uses this information to determine whether there are certain problems occurring. If your results show the potential for other health conditions, this will guide your doctor in choosing which tests will be required for a complete diagnosis.
There are several factors than can affect the results of your lab tests. Your age, race, and gender often have a significant impact on lab tests, which is why some tests may only be prescribed for males or females. Results can also be affected by your current health problems, any medications you are taking, foods, and whether you followed the instructions properly to prepare.
Lab tests are an important part of medical treatment. While they may be bothersome to some people, the information they provide can have a huge impact on your health.
