What's this test for?

This test is ideal if you're experiencing muscle weakness, nausea, or unusual symptoms after working around pesticides, chemicals, or certain medications. It's also useful if you're concerned about liver function or have been exposed to nerve-affecting substances at work or home. The test checks how well a key enzyme in your blood is working, which can be affected by toxins, liver problems, or genetic factors.

What happens after I get my results?

Your results will show up in your account with each value's normal range clearly explained, so you can see exactly where you stand. If your enzyme levels are outside the expected range, simple next steps might include avoiding further chemical exposure, giving your body time to recover, or retesting after a few weeks to check progress. If a result comes back significantly low, it's important to seek medical care right away since this can signal serious exposure. You can download a standard lab report anytime, and use the trends feature to track your enzyme levels over time.

Who should consider this test?

People who work with pesticides, insecticides, or industrial chemicals should consider this test as part of routine health monitoring. It's also useful for anyone who has had recent symptoms like blurred vision, excessive sweating, or muscle twitching after chemical exposure. People taking certain medications that affect nerve or muscle function may also benefit from checking this enzyme.

What symptoms indicate I may need this test?

Watch for symptoms like unexplained muscle weakness, twitching, excessive sweating, nausea, or trouble breathing, especially after handling chemicals or pesticides. Blurred vision, drooling, or stomach cramps can also be warning signs worth checking out. If you work in agriculture, pest control, or manufacturing and notice these symptoms, this test can help clarify what's going on.

When will I get my results?

Results are typically ready within about 7 days after your sample is collected at the lab. Once ready, they'll be posted directly to your online account where you can view and download them. You'll be able to see your enzyme levels alongside the normal reference range right away.

What is cholinesterase and why does it matter?

Cholinesterase is an enzyme in your blood that helps your nervous system and muscles communicate properly. It's especially important because certain pesticides and chemicals can block this enzyme, leading to serious nerve and muscle problems if levels drop too low. Checking this enzyme helps catch chemical exposure or certain health issues before they become more serious.

What does low cholinesterase mean?

Low cholinesterase can mean you've been exposed to pesticides or certain chemicals that interfere with nerve signaling, or it could point to liver problems since your liver makes this enzyme. Symptoms like muscle weakness, sweating, or nausea alongside low levels are worth taking seriously. If your level is very low, seek medical care promptly, since this can affect breathing and muscle control.

What causes high or low cholinesterase levels?

Low levels are often linked to pesticide or chemical exposure, liver disease, or certain genetic traits that naturally lower enzyme production. High levels can sometimes occur with conditions like high blood pressure, diabetes, or excess body fat, though they're less commonly a health concern. Certain medications can also shift your levels in either direction.

How often should I retest?

If you work regularly with pesticides or chemicals, retesting every few months is a reasonable way to monitor your baseline enzyme levels over time. After a known chemical exposure, retesting a few weeks later can help confirm your levels are recovering. Your trends dashboard makes it easy to compare results side by side.

What should I do if my results are abnormal?

If your results are outside the normal range, start by reviewing any recent chemical or pesticide exposure and try to limit further contact with these substances. Give your body time to rest and recover, stay hydrated, and support your liver with a balanced diet. If your levels are very low or you have symptoms like muscle weakness or trouble breathing, seek medical care right away.
