Confirmatory analysis, verification and quantification of drug tests via accredited Swedish laboratories. GC-MS and LC-MS/MS as standard – these are the results that hold up legally in work environment cases and disputes.
Fast handling from sample arrival to digital report.
Swedish accreditation – holds up in the Labour Court.
Mass spectrometry as standard for confirmation.
Positive results are reviewed before reporting.
The sealed sample is received at an accredited laboratory. The integrity of the seal is checked and documented on receipt.
Screening is based on antibody binding. Negative results are reported directly; positive results proceed to confirmation.
Mass spectrometry identifies the substance specifically and quantitatively. Immune to cross-reactions that cause false positive results.
An MRO physician reviews the result and contacts the tested person to investigate legitimate medical explanations.
The final result is delivered digitally in Provsvaret's encrypted portal to the authorised HR recipient.
We explain what the confirmatory method itself involves in What is LC-MS/MS in drug testing?
5-, 10- and extended panels. Includes amphetamine, cocaine, opiates, benzodiazepines, THC, buprenorphine, methadone, MDMA, oxycodone, tramadol and NPS in the extended panel.
PEth (phosphatidylethanol), CDT (carbohydrate-deficient transferrin) and EtG (ethyl glucuronide) in blood, urine or hair. Consumption patterns over 2–4 weeks.
Exact concentration measurement for medical investigations and legal disputes. Quantitative analysis with a blood test gives the highest precision.
Confirmatory analysis of positive rapid tests from the workplace. Read more about the entire chain of custody.
Screening is an initial analysis based on antibody binding – fast and inexpensive, but it can give false positive results due to cross-reactions. Confirmatory analysis with GC-MS or LC-MS/MS identifies the substance specifically and quantitatively – immune to cross-reactions and legally robust.
