Therapeutic Drug Monitoring Lab Testing

If you need the levels of a particular medication monitored, then Affordable Laboratory Services can help. Whether a doctor has asked you to get your levels of a prescribed drug checked, or you'd just like to know for yourself what the levels are, we can run these tests at any of our labs locations.


Why The Test is Suggested:

When someone is first prescribed a particular medication, it's common that their levels for that drug be tested. With the results of this testing, a doctor or other health care physician can tell if the dosage needs to be increased or decreased.


As you may already know, not all drugs work the same for all people. Sometimes, not enough of a particular medicine can reach a person's bloodstream. Some people's body's absorb or use particular drugs much different than others, especially related to their health status.


Tests may be done frequently to make sure that the medication is helping, or if the dosage needs to be reduced if there are extreme side effects or other signs of toxicity. Since it can take time for levels of certain drugs to stabilize, a doctor may request that several tests are done over the course of a few weeks. In some cases, a physician may decide to switch to a different drug altogether, if a new drug better fits a person's medical condition.


Examples of Drugs We can Test Levels of:


Our lab is able to test or frequently monitor the levels of heart medications, antibiotics, psychiatric drugs, anti-cancer drugs, bronchodilators (asthma), epilepsy drugs, and much more. 


We're able to test levels for a wide variety of prescribed drugs, but below you will find some of our most commonly performed tests:
