The Phenytoin (Dilantin) test is a specialized blood test used to measure the level of phenytoin in the bloodstream. Phenytoin is a commonly prescribed anti-epileptic medication used to control seizures in patients with epilepsy and other neurological conditions. Monitoring phenytoin levels is essential because the drug has a narrow therapeutic range—meaning that both low and high levels can cause serious health problems.
At Ibn-E-Sina Clinical Laboratory, this test is performed using advanced diagnostic equipment and strict quality control standards to ensure accurate and reliable results. Known across Pakistan for its trusted diagnostic services, Ibn-E-Sina Clinical Laboratory plays a crucial role in helping doctors safely manage long-term anti-seizure therapy.
Whether you are starting phenytoin treatment, adjusting your dosage, or experiencing side effects, the Phenytoin (Dilantin) test at Ibn-E-Sina Clinical Laboratory helps your healthcare provider make informed treatment decisions. This article provides complete details about the test, including its purpose, preparation, procedure, normal values, cost, and booking options in Pakistan.
What is the Phenytoin (Dilantin) Test?
The Phenytoin (Dilantin) test, also known as Phenytoin Total or Phenytoin Free, measures the amount of phenytoin present in your blood. Phenytoin works by stabilizing electrical activity in the brain, preventing abnormal nerve firing that leads to seizures.
There are two main types of phenytoin measurements:
- Total Phenytoin: Measures both bound and unbound drug in the blood.
- Free Phenytoin: Measures only the active (unbound) portion of the drug.
Doctors usually recommend this test to:
- Monitor seizure control
- Adjust medication dosage
- Prevent phenytoin toxicity
- Check medication compliance
The Phenytoin (Dilantin) test at Ibn-E-Sina Clinical Laboratory is widely used for patients on long-term anticonvulsant therapy.
Why is the Phenytoin (Dilantin) Test Important?
Phenytoin levels must be carefully monitored because small changes in dosage can significantly affect blood concentration. Too little phenytoin may lead to uncontrolled seizures, while too much can cause toxicity.
This test is important because it:
- Ensures effective seizure control
- Prevents drug-related side effects
- Helps tailor treatment for individual patients
- Monitors drug interactions with other medications
Symptoms of abnormal phenytoin levels may include dizziness, confusion, slurred speech, nausea, or difficulty walking. Regular testing at Ibn-E-Sina Clinical Laboratory helps doctors maintain safe and effective therapy.
