Can Poor Breath-Test Effort Understate Serum Alcohol? What 480 Emergency Patients Show
In 480 emergency patients, poor breath-test effort correlated less strongly with measured serum alcohol. Learn why no individual BAC correction follows.
Can One Evening of Alcohol Change Intestinal-Barrier Blood Markers for 48 Hours? A 22-Volunteer Study
A 22-person alcohol study measured serum I-FABP and sCD14 for 48 hours. Examine observed results, serum BAC distinctions and limits on infection causation.
Can a Light Meal Make Breath Alcohol Peak Timing Too Variable for Straight-Line Back-Calculation? A 52-Person Study
A 52-person breath-alcohol study found peak times spanning 17–109 minutes. See what gamma modeling can—and cannot—prove in forensic BAC reconstruction.
Can a Widmark Calculation Imply More Than 100% Alcohol Absorption? An Eight-Man Model Comparison
A model-derived ‘105% absorption’ is not a physical test result. See the 8-man serum ethanol study and why model-based BAC estimates require caution.
When AST and ALT Show No Group Difference, Can Other Blood Markers Respond to Alcohol? A 40-Person Trial
A 40-person alcohol trial found no group difference in AST/ALT but reported serum, lipid and vital-sign changes. What the evidence cannot prove.
Does Alcohol Make Unknown-Odds Choices More Appealing? What a 100-Person Bar Study Found
A 100-person bar study linked breathalyzer readings to unknown-odds choices. Learn why it cannot establish individual impairment, intent or causation.
Can Gastric-Emptying Drugs Change Alcohol Exposure? What an Oral-vs-IV Trial Found
A 16-volunteer alcohol study found that gastric-emptying drugs altered oral ethanol availability; only 7 had matched first-pass comparisons. Read the forensic limits.
Can an Online BAC Calculator Establish a Driver’s Blood Alcohol Level? A 36-Calculator Study
A 2026 study compared 36 online BAC calculators with reference data. See reported errors, missing inputs, and why a web estimate cannot establish individual BAC.
Can a ‘Very Low Crash Risk’ Screen Miss Speeding After Drinking? A 16-Driver Study
A 16-driver pilot found more simulated speeding and mistakes at falling alcohol levels although UFOV still rated crash risk ‘very low.’ Read exact limitations.
Can a Hangover Disrupt Word Recognition and Tracking at Zero Breath Alcohol? A 25-Person Study
A 25-person study found more word-recognition errors and selected tracking costs during hangover despite 0.00% morning breath alcohol. See its limits.
Does Drinking Water Between Alcoholic Drinks Prevent a Hangover? A 13-Man Trial
A 2026 crossover trial tested extra water with a fixed ethanol dose. Learn what breath ethanol, acetaldehyde, hangover ratings and DSST actually showed.
Can One Drinking Episode Push PEth Above 20 ng/mL? A 12-Person Trial
A controlled 12-person trial found PEth above 20 ng/mL after one drinking session. Examine serum BAC, dried blood spots, assay limits and forensic uncertainties.
Can a Postmortem Ethanol Result Be Falsely Low? Microbial Oxidation and an HS-GC–MS Study
Can microbes lower ethanol in a postmortem blood sample? A primary GC–MS study examines labeled-standard loss, specimen instability, and forensic uncertainty.
Can a Wrist Reaction-Time Sensor Prove Alcohol Impairment? A 19-Person Pilot Study
A 19-person alcohol study linked wrist reaction times to breath readings. See why the sensor does not yet establish BAC, driving impairment, or causation.
Can a Breath Alcohol Slope Detector Rule Out Mouth Alcohol? Three Case Reports
Three DataMaster DMT cases show why a breath slope-detector non-alert cannot conclusively exclude mouth alcohol. Understand waveform and forensic limits.
Can Older Adults Underestimate Alcohol-Related Test Slowing? A Placebo Trial
A 68-person alcohol/placebo trial compared older and younger drinkers’ Trail Making times and perceived impairment. What the findings do—and do not—prove in court.
Does a Higher Breath Alcohol Peak Predict an Arrhythmia? A 193-Person Holter Study
In 193 binge drinkers, higher breath alcohol correlated with heart rate and HRV, but arrhythmia rates did not differ across exposure groups. See limits.
Can Monocyte Changes Persist After Blood Ethanol Is Undetectable? A 48-Hour Human Study
A 22-person study found monocyte and TLR4 changes after ethanol was undetectable. Learn what the blood assay measured—and why it cannot prove infection or impairment.
Can Overnight Heart Rate After Alcohol Prove Next-Day Impairment? A Sleep-Lab Study
In a controlled study, alcohol raised sleeping heart rate and altered REM sleep—but those changes did not predict next-day task effects. See the forensic limits.
Does a Positive Beer Biomarker Prove Alcohol Consumption? Why Isoxanthohumol Also Follows Nonalcoholic Beer
Urine isoxanthohumol can follow alcoholic or nonalcoholic beer. Review the 33-person evidence, hop-marker limits and why it cannot establish BAC or impairment.
Can Acute Alcohol Change White Blood Cell Function Without Proving a Trauma Infection?
A 22-volunteer study measured leukocyte phagocytosis, ROS and caspase markers after drinking. Learn why BAC and cell assays cannot prove a trauma infection was alcohol-caused.
Can a Year-Old DUI Blood Alcohol Retest Match the Original—and Does Glass Versus Plastic Matter?
Can an archived DUI blood-alcohol sample retest lower after 12 months? A whole-blood HS-GC study compares ethanol loss in glass versus plastic tubes.
Can Brain MRI Show How Drunk Someone Feels? What an Alcohol-Challenge Study Can—and Cannot—Establish
A study of 89 social drinkers linked MRI gray-matter density with self-rated alcohol effects. Why those findings cannot determine BAC, driving impairment or causation.
Can a Drinking Denial Rule Out Blood Alcohol? A 201-Case Study
A 201-case poisoning study compared recorded drinking history with clinical blood ethanol results. Examine 2×2 counts, missing histories and forensic limits.
Can a Bayesian Model Reconstruct Breath Alcohol from a Skin Monitor? Why Its Uncertainty Band Matters
What does a skin alcohol monitor prove? A 2021 Bayesian study shows why transdermal readings and credible bands cannot establish precise individual BrAC or BAC.
Can Falling AST or ALT Rule Out Alcohol Exposure? What a 0.5% Beverage Trial Shows
In a 42-person crossover study, AST and ALT fell during low-dose alcohol exposure, but between-period changes were not significant. Learn the forensic limits.
Can an Alcohol Skin Swab Falsely Elevate a Blood Alcohol Result? A Controlled Venipuncture Study
