Whats the difference between a 6 panel drug test and a 7 panel?

Question

and do either of them test for alcohol?

Answer 1

Alcohol / ETOH is not typically tested for in a "Drug Screen". Hope the rest of this information helps.

The ProScreen® Multi-Drug 6 Panel Test is an forensic, all inclusive, point of use  screening test for the rapid detection of THC (Marijuana), Cocaine and its metabolite, benzoylecgonine, Morphine and its related metabolites derived from opium (opiates), Oxycodone (Percodan, Percocet, Roxicodone, Oxycontin), Methamphetamines (including Ecstasy), and Benzodiazepines (Xanax, Valium etc.), in human urine at or above the system concentrations levels established as standard minimums by the National Institute on Drug Abuse (NIDA), the World Health Organization (WHO) and SAMHSA. This test is also recommended for an all inclusive scan when drug use is suspected but the specific target drug is unknown. Results are obtained within 8 minutes and are 98% accurate when instructions are followed precisely.

The ProScreen® 7 Multi-Drug Panel Test Card is an all inclusive screening test card for the detection of seven drugs and drug metabolites simultaneously; THC (Marijuana), Cocaine and its metabolite, benzoylecgonine, Opiates, Oxycodone (Percocet, Percodan, Oxycontin), Methamphetamines (including Ecstasy), Benzodiazepines (Xanax, Valium etc.), and Barbiturates in one simple test device. With this one test, approximately 75% of illicit and prescription drugs of abuse are detected at the standard sensitivity cutoff levels established by the National Institute for Drug Abuse (NIDA) and the World Health Organization (WHO). This test is also recommended for an all inclusive scan when drug use is suspected but the specific target drug is unknown.Results are obtained within 8 minutes and are 98% accurate when instructions are followed precisely
