What's this test for?

This test is ideal if you're currently taking chlorpromazine for psychosis or Tourette's syndrome and need to make sure your dose is working correctly. It helps check whether the amount of medication in your blood is in a safe and effective range. This is especially useful if you're experiencing side effects, feel like the medication isn't working as well as it should, or need to confirm you're taking it as prescribed.

What happens after I get my results?

Your results will be available in your account, with the normal range for chlorpromazine clearly explained next to your value. If your level is outside the expected range, the report will help you understand whether it may be too high, which raises the chance of side effects, or too low, which may mean the medication isn't working as intended. You can download a standard lab report from your account at any time, and use the trends feature to track your levels over multiple tests to see how your body is responding over time. If your result is significantly abnormal, seek medical care promptly.

Who should consider this test?

Anyone taking chlorpromazine regularly for psychosis or Tourette's syndrome should consider this test, especially if a dose was recently changed. It's also useful if you've noticed new side effects, feel your symptoms aren't well controlled, or want to confirm the medication is being absorbed and used properly by your body. Regular monitoring can help catch problems early before they become serious.

What symptoms indicate I may need this test?
Consider this test if you're noticing drowsiness, dizziness, muscle stiffness, tremors, or an irregular heartbeat, which can be signs the medication level is too high. On the other hand, if your original symptoms of psychosis or tics are returning or getting worse, that could mean your level is too low. Either situation is a good reason to check your blood level.
What is chlorpromazine and why does it matter?
Chlorpromazine is a medication that helps calm overactive signals in the brain, and it's commonly used to manage psychosis and the tics associated with Tourette's syndrome. Because everyone's body processes medications differently, the same dose can lead to very different blood levels from person to person. Checking your level matters because too little won't control your symptoms, while too much can cause uncomfortable or even dangerous side effects.
What does high chlorpromazine mean?
A high level means there's more of the medication in your blood than expected, which raises your risk of side effects like severe drowsiness, low blood pressure, muscle stiffness, or heart rhythm changes. This can happen if the dose is too high for your body or if you're taking it more often than prescribed. If your level comes back high, especially with symptoms like fainting or an irregular heartbeat, seek medical care right away.
What does low chlorpromazine mean?
A low level often means the medication isn't reaching a strong enough amount in your blood to control your symptoms effectively. This can happen if a dose is missed, taken inconsistently, or if your body breaks the medication down faster than average. If your symptoms are also coming back, this is a sign the current routine may need to be adjusted.
What causes abnormal chlorpromazine levels?
Missing doses, taking the medication at inconsistent times, or not following the prescribed schedule are common causes of an abnormal reading. Other factors like liver function, other medications you're taking, smoking, and even diet can affect how your body processes chlorpromazine. Genetic differences also mean two people on the same dose can end up with very different blood levels.
How often should I retest?
Retesting is often done after any dose change to confirm the new amount is having the intended effect, typically after your body has had time to reach a steady level. Beyond that, periodic checks every few months can help make sure your levels stay stable over time, especially if your symptoms or side effects change. Use the trends feature in your account to keep an eye on any patterns.
What should I do if my results are abnormal?
Start by reviewing the pre-collection instructions and confirming you took your last dose as usual before the test, since timing affects the reading. Keep a simple log of your dosing schedule and any symptoms or side effects to spot patterns. If your result is far outside the normal range or you're having concerning symptoms like severe dizziness or an irregular heartbeat, seek medical care as soon as possible.

What this means

This sample result falls within the therapeutic range, meaning the medication level is generally considered effective without being excessive. Levels within this window are typically associated with symptom control while keeping the risk of side effects lower. Values above this range may increase the chance of side effects, while values below it may mean symptoms aren't well controlled.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
