The main purpose of the blood test for phenytoin is to measure blood levels of the drug. This helps determine whether the dose is within the therapeutic range. Phenytoin is commonly used to control seizures , and maintaining the correct dosage is crucial to remaining seizure-free without suffering from toxic effects.
Taking phenytoin can cause side effects, such as dizziness , drowsiness, problems with coordination and gum disease. A blood test can help detect signs of toxic effects and optimize the dose to minimize side effects.
You do not need to fast for this blood test.

How accurate is the Fenytoine blood test?
The accuracy of the test for Fenytoine is conducted through ISO-certified laboratories. The accuracy of a test method is expressed in terms of specificity and sensitivity. However, the most important aspect is that the results are interpreted and accepted among general practitioners and hospitals. This is the case with our venous samples. Mutual acceptance may not always be present due to potentially reduced reliability with a capillary sample.
How long does it take to receive the results of a Fenytoine blood test?
Most tests generally take 24-48 hours. Tests that go through an LC-MS method generally take longer, think about an average of 3-7 working days. Additionally, it also depends on the location. Some locations do the analysis themselves and others outsource it to another lab.
How do I interpret the results of a Fenytoine blood test?
Interpreting the results of Fenytoine is not always easy and should be seen in the broader picture, along with anamnesis and physical examination. In the doctor's advice section, the query in which you can already outline your complaints is taken into account, otherwise, the results are interpreted in conjunction with the other results. If necessary, the doctor can call to ask about physical abnormalities. You don't have to interpret the results yourself because there is always advice and explanation from the doctor.

For blood tests, we always use venous sampling. This is the gold standard for blood collection. Over-the-counter tests, such as a finger prick test, use the capillary route for blood collection. These do not always give the same results and the accuracy depends on how, where, and with which technique the collection is done. The advantage, of course, is that the test is easier and less painful to take.
