Anesthetics Metabolism
Some people wake up from anesthesia quickly and clearly; others are groggy for hours or experience prolonged side effects. Your clearance rate predicts which camp you're in—valuable information before any procedure requiring sedation.
What this measures
How your DNA shapes anesthetics metabolism.
The CYP3A4, CYP3A5, CYP2D6, and CYP2B6 family handles the bulk of anesthetic clearance — from propofol (CYP2B6) to fentanyl (CYP3A4) to codeine and tramadol (CYP2D6). Each enzyme runs on its own variant set, which is why one client can clear propofol quickly and codeine slowly, or vice versa.
Carriers of CYP2D6 reduced-activity variants ("poor metabolizers") are associated with significantly reduced effect from codeine (which depends on CYP2D6 for conversion to morphine) and prolonged effect from tramadol. Carriers of CYP2D6 high-activity variants ("ultrarapid metabolizers") are associated with the opposite pattern — and elevated risk of opioid toxicity from codeine. CYP3A5 expression status splits along ethnic lines and shifts intraoperative dosing meaningfully.
Co-administered medications and certain foods (grapefruit juice inhibits CYP3A4 for up to 72 hours) shift effective clearance further. Stress, recent illness, and liver function all influence enzyme activity acutely. Genotype-aware dosing — used routinely in some clinical contexts — meaningfully reduces complication rates.
Surgical anesthesia is the rare scenario where pharmacogenomics changes immediate, life-affecting outcomes. Which CYP combination you carry decides whether standard dosing fits or whether the anesthesia team has reason to adjust — information that belongs in the conversation before any planned procedure.
Anesthetics Metabolism is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the detoxification pathways spectrum — and what you can do about it.

Where Anesthetics Metabolism lives inside your Genomic Lifestyle Optimization Report.
Anesthetics Metabolism renders as a dark-background card with a color marker calibrated to your specific variants. The card opens with the gene mechanism, shows your result at a glance via that marker, and closes with a practical, mechanism-led recommendation — what to eat, what to time, what cofactors to support.

In context
Breakdown of Medications: the 4-insight cluster.
Anesthetics Metabolism is one finding in a tightly-related cluster. Mosaic sequences the other 3 alongside it so you see the whole biology — not an isolated data point.
- Acetaminophen MetabolismYour liver clears Tylenol at its own pace—fast, intermediate, or slow. If you're a slow processor, standard doses linger longer than they should, and "take two every four hours" might be too much for your system. This guides safe dosing and prevents accidental overload.
- Medication MetabolismThe enzyme family that processes roughly half of all prescription drugs. Your version determines whether standard doses work perfectly, cause side effects, or barely register. This prevents the trial-and-error prescribing that leaves people cycling through medications, wondering why nothing works right.
- NSAIDS MetabolismIbuprofen, aspirin, and naproxen—your clearance rate for these common pain relievers varies. Slow metabolizers face higher GI bleeding and cardiovascular risk at doses that are perfectly safe for fast metabolizers. This is the kind of information that should come before chronic use, not after complications.
Questions people ask
About Anesthetics Metabolism.
- How does my DNA influence anesthetics metabolism?
- Phase I (CYP450 enzymes), Phase II (sulfation, glucuronidation, methylation), and Phase III (transport) — the three-act process by which your body neutralizes everything from caffeine to alcohol to environmental compounds. Genetic variants in any phase shift the kinetics, and the bottleneck moves accordingly.
- What kind of test do I need to see my Anesthetics Metabolism result?
- Whole-genome sequencing at 30× clinical depth. Consumer SNP-chip tests like 23andMe or AncestryDNA only read ~0.02% of your DNA and miss most of the variants this analysis needs. Mosaic reads all 3 billion base pairs and produces the full 108-insight report.
- How is Anesthetics Metabolism different from clinical lab testing?
- Clinical labs measure downstream biomarkers — blood levels, hormone values, metabolic byproducts — at a single point in time. Genomic insights like Anesthetics Metabolism reveal the underlying variant that shapes the biology, which is constant for life. The two are complementary: labs show the current snapshot; genomics shows the long-term tendency and where lifestyle leverage is highest.

Acetaminophen Metabolism
Your liver clears Tylenol at its own pace—fast, intermediate, or slow. If you're a slow processor, standard doses linger longer than they should, and "take two every four hours" might be too much for your system. This guides safe dosing and prevents accidental overload.

Acetylation
This pathway handles histamine, caffeine, and a long list of chemicals and medications. Slow acetylators often experience fragrance sensitivity, medication side effects, or react to things that most people tolerate. Once you know, you can support the bottleneck instead of wondering why everything bothers you.

Glutathione Support Needs
Glutathione is your body's master antioxidant—the one that recycles all the others. Some people produce plenty; others run chronically low without knowing it. Lower genetic output is common and responds well to precursors like NAC, glycine, and selenium. This is often the missing piece for people who "do everything right" but still feel run down.

MTHFR Activity
MTHFR converts synthetic folic acid into the active methylfolate your body uses. Reduced function is common, affecting up to 40% of people. If you're one of them, standard prenatal vitamins and fortified foods won't cut it. Methylfolate supplementation bypasses the bottleneck entirely.

Methylation
Methylation is the behind-the-scenes regulator of detox, neurotransmitter production, and gene expression. Suboptimal activity is surprisingly common—and highly responsive to the right form of B-vitamins. If you've ever taken B-complex and felt nothing (or worse), this is probably why.
