What's this test for?

This test is ideal if you're currently taking a prescribed antidepressant and need to confirm that your medication levels are on track. It helps show whether the prescribed drug is present at an expected level and checks for other non-prescribed substances. This can be useful if you or someone monitoring your care wants documented proof of medication adherence.

What's included in this test?

This test screens for the presence and level of prescribed antidepressant medication in your blood, along with a confirmation step to verify accuracy. This matters because it helps confirm you're taking your medication as prescribed and that no unexpected substances are present, which supports safer, more consistent treatment tracking.

What happens after I get my results?

Your results will show up in your account with an explanation of what a normal versus abnormal range looks like for each substance tested. If your prescribed medication level looks unusually low or high, simple next steps include reviewing your dosing schedule and timing of your last dose before retesting. Severe symptoms like fainting, confusion, or breathing trouble should prompt immediate emergency care rather than waiting on results. You can download a standard lab report from your account anytime and use the trends feature to track your levels over multiple tests.

Who should consider this test?
Anyone currently prescribed an antidepressant who wants documented confirmation that their medication levels are within an expected range should consider this test. It's also useful for people who've had recent dose changes and want to verify their body is responding as expected. This test can be a helpful check-in tool between prescription changes.
What symptoms indicate I may need this test?
If you're experiencing side effects that feel stronger than expected, or your symptoms haven't improved despite taking your medication consistently, this test can help clarify what's happening in your body. Sudden changes in mood, energy, or sleep after a dose adjustment are also good reasons to check your levels. It's also useful if you're unsure whether your medication routine is being followed as intended.
How can I naturally support healthy mood and treatment response?
Alongside your prescribed treatment plan, regular sleep, consistent exercise, and reducing alcohol intake can support how well your body responds to antidepressant medication. Eating balanced meals at consistent times can also help medication absorption stay steady. These habits won't replace your prescribed treatment, but they can support more consistent results over time.
When will I get my results?
Results are typically ready within about 7 days of your sample being tested. You'll receive a notification once they're available, and you can log into your account to view the full breakdown at that time.
What does a low medication level mean?
A lower-than-expected level of your prescribed antidepressant could mean the dose isn't being taken consistently, or that your body processes the medication faster than average. This is worth noting and discussing with whoever manages your prescription, since it may affect how well the medication is working for you. Tracking this over time with repeat testing can help spot patterns.
What does a high medication level mean?
A higher-than-expected level might mean the dose is being taken more frequently than prescribed, or that your body clears the medication more slowly than average. This isn't necessarily dangerous, but very high levels paired with symptoms like severe drowsiness, confusion, or irregular heartbeat should be treated as urgent and may require immediate medical attention. Retesting after confirming your dosing routine can help clarify the reason for the change.
How often should I retest?
Retesting frequency depends on your specific treatment plan, but many people check in every few months or after any dose change. If you've recently started a new medication or adjusted your dose, retesting a few weeks later can help confirm your levels have stabilized. Using the trends feature lets you see how your levels shift over time.

Sertraline (Serum Level) 55 ng/mL
Demo results
Sub-therapeutic Therapeutic Range Above Therapeutic
55 ng/mL

What this means

A level of 55 ng/mL falls below the typical therapeutic range for sertraline, suggesting the medication may not be at a level expected for consistent daily dosing. This could mean a missed dose, inconsistent timing, or a faster metabolism. It doesn't necessarily mean the medication isn't working, but it's worth reviewing your dosing routine.

* 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.
