What's this test for?

This test is ideal if you're experiencing symptoms like excessive sweating, muscle tremors, confusion, or stomach cramps after working around pesticides or other chemicals. It's also useful if you or a family member has a history of unusual reactions to muscle relaxants used during surgery. Farm workers, pesticide applicators, and people with a family history of anesthesia complications often use this test to check their risk before problems occur.

What's included in this test?

This test measures serum cholinesterase, an enzyme your body needs to break down certain chemicals and medications. Checking this single marker matters because it can reveal recent chemical exposure or an inherited condition that affects how your body processes certain surgical drugs.

What happens after I get my results?

Your results will appear in your account with an explanation of the normal range for cholinesterase so you can see exactly where your number falls. If your level is low, next steps may include avoiding further pesticide exposure, retesting periodically to track recovery, and using protective equipment when working with chemicals; if your level is dangerously low or you have symptoms of poisoning, seek medical care right away. You can download a standard lab report from your account at any time, and the trends feature lets you track your cholinesterase levels over multiple tests to see if they're improving or worsening.

How can I naturally support healthy cholinesterase levels?

The best way to protect your cholinesterase levels is to limit contact with pesticides and organophosphate chemicals by wearing gloves, masks, and protective clothing when working with them. Eating a balanced diet that supports liver health, since cholinesterase is produced in the liver, can also help your body recover after exposure. Staying hydrated and avoiding alcohol during recovery periods gives your liver a better chance to rebuild enzyme levels naturally.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification as soon as your report is available in your account, so you don't need to check repeatedly. If your results suggest a urgent concern, follow the safety guidance provided with your report.

Who should consider this test?

This test is a good fit for anyone who works directly with pesticides, such as farm workers, landscapers, or pest control technicians, especially if they want a baseline reading before regular exposure begins. It's also worth considering if you have a family history of pseudocholinesterase deficiency and are preparing for a surgery that involves muscle relaxants. People who've experienced unexplained symptoms like excessive sweating, confusion, or muscle weakness after chemical exposure may also benefit.

What symptoms indicate I may need this test?

Symptoms like heavy sweating, excessive saliva, small pupils, muscle twitching, confusion, stomach cramps, and unusual anxiety after handling chemicals can all point to a need for this test. If you or a family member had an unusually long recovery from anesthesia after surgery, that's another sign worth checking. Severe symptoms like difficulty breathing or seizures require immediate emergency care, not just testing.

What does low cholinesterase mean?

A low cholinesterase level often points to recent exposure to organophosphate pesticides, since these chemicals block the enzyme's normal function. It can also be a sign of an inherited pseudocholinesterase deficiency, which affects how your body processes certain anesthesia drugs. Either way, a low result is worth taking seriously, especially if you have upcoming surgery planned or continued exposure to chemicals at work.

What causes low cholinesterase levels?

The most common cause is exposure to organophosphate pesticides or similar chemicals, which interfere with how the enzyme works in your body. An inherited genetic variation can also cause naturally lower levels that run in families, independent of any chemical exposure. Liver conditions can sometimes lower cholinesterase too, since the enzyme is produced in the liver.

How often should I retest?

If you work regularly with pesticides, retesting every few months, or right after any known heavy exposure, is a reasonable approach to track changes over time. Once you've established a personal baseline, comparing future results against it makes it easier to catch problems early. If you're testing due to a family history of pseudocholinesterase deficiency, one baseline test is usually enough unless your situation changes.
