Interpretation results

POSITIVE

T1, T2, T3, T4, T5 and T6 BANDS NOT VISIBLE.

The test is positive when a band appears next to the C (control) mark and no band appears at the corresponding T mark.

You should not undertake any action requiring sustained attention or concentration such as driving a vehicle.

NEGATIVE

T1, T2, T3, T4, T5 and T6 BANDS VISIBLE.

The test is negative when a band appears next to the C (control) mark and a band also appears at the corresponding T mark. The intensity of the bands varies. A T1, T2, T3, T4, T5, or T6 band, even if very faint, indicates a negative result. 

INVALID

BAND C NOT VISIBLE

The test is invalid when the control band (C mark) does not appear. This most often occurs when the instructions in the package insert are not followed. Read the instructions and start again with a new test.

QUESTIONS & ANSWERS

How does the Medisur MULTI-DRUG SALIVARY TEST work? 

Using antibodies against cocaine, methamphetamines, Δ9-THC, amphetamines, opiates, and K2, MULTIDRUG SALIVARY TEST reveals the presence of one or more of these drugs. If the concentration of these compounds rises to a certain threshold, the test is positive.

When can it be done? 

The test can be performed on a saliva sample obtained at any time of day. However, you should not eat, drink, or smoke for 10 minutes before taking the test.

What is the detection time for cocaine, methamphetamines, cannabis, amphetamines, opiates, amphetamines and K2 in saliva? 

the MULTIDRUG SALIVARY TEST Medisur allows to detect the consumption of: 

– Cocaine: 5 to 10 minutes up to 24 hours after consumption depending on the dose.

– Methamphetamines: 5 to 10 minutes up to 72 hours after consumption depending on the dose.

– MDMA: 5 to 10 minutes up to 10 hours after consumption.

– Cannabis: 30 minutes to 12 hours on average. Detection time varies depending on consumption. 

– Opiates: 1 hour to 7-9 p.m. after consumption depending on the dose.

– Amphetamines: 5 to 10 minutes up to 72 hours after consumption depending on the dose.

– Synthetic cannabinoids: 30 minutes to 12 hours on average. Detection time varies depending on consumption.

Can we get wrong results? 

For the test to be reliable, the instructions in the package leaflet must be followed carefully. The quantity and quality of the saliva collected will be decisive for obtaining a correct result. Indeed, the result can be distorted if the test is wet before taking it, or if the quantity of saliva impregnated by the test is not sufficient. It is therefore important to remove the saliva collector only when the saturation indicator has turned pink/red.

I didn't apply enough saliva to the Medisur MULTIDRUG SALIVARY TEST. Will I get an accurate result? 

No, if the saliva volume is not sufficient, the test may give a false negative or be invalid.

What is the purpose of the strip that appears next to the C (Control) mark?

If the line next to the C mark appears, it means the Medisur multidrug saliva test worked. If the line next to the C mark does not appear, it means the test did not work. You should then start again with a new test.

I read the result after 20 minutes. Will I get a reliable result? 

No, the positive result must be read 10 minutes after the test is performed. MULTIDRUG SALIVARY TEST from Medisur. A negative result can be read after 2 minutes, according to the test instructions given in the package insert. After 20 minutes, the interpretation of results is no longer reliable.

How to interpret the test if the intensity of the T1, T2, T3, T4, T5 and T6 bands are different?

The intensity of the bands is of no importance for reading the results. The bands must only be homogeneous and continuous. The appearance of low-intensity T1, T2, T3, T4, T5, and T6 bands is considered a negative result.

What should I do if the result is positive? 

If the result is positive, it means that the test detected one or more drugs in the saliva. You should not undertake any action requiring your full attention or concentration, such as driving a vehicle.

What should I do if the result is negative? 

If the result is negative and you have not used drugs, there are no special precautions to take.

IMPORTANT

A negative result does not necessarily mean that the sample does not contain any psychoactive substances. Substances below the test's detection threshold may be present in the saliva sample.

IF IN DOUBT, DON'T DRIVE!
