In order to avoid skincontact of the Sniffin’ Sticks you can use these cellulose paper strips for smell testing. You can use these strips in combination with the following Sniffin’ Sticks tests:

  • Sniffin’ Sticks identification tests (blue and purple)
  • Sniffin’ Sticks Screening 12 Test
  • Sniffin’ Sticks discrimination test

Cellulose paper strips for smell testing

The cellulose paper strips are available in the following packages:

  • LA-13-00419 Cellulose Paper Strips: tube with 50 strips and 1 tweezer, € 32,- (excl. VAT)
  • LA-13-00420 Cellulose Paper Strips, 4 sheets with 25 strips each (100 strips in total), € 30,- (excl. VAT)

Procedure for using the paper strips

The smell test is used according to its respective manual. The patient is presented the prepared smell paper instead of the Sniffin’ Stick.

  • Prepare clean support, e.g. a sheet of paper or paper towel
  • Use a single paper strip
  • You can open the Sniffin’ Stick in the test area at a sufficient distance from the patient. You take a paper strip (preferably with tweezers) and draw a stripe of about 2 cm on the paper strip with the Sniffin’ Stick.
  • Paint approximately 2 cm of odor with the Sniffin’ Stick on the tip of the filter paper once
  • Present the prepared paper stripe within 5 minutes to the test person
  • The examiner hands the paper over to the test person and the test person smells the line on the paper and answers the question. The paper strip can then be discarded and the procedure can be repeated for the next stick.
  • Use the same spot on the support only once

Best before date

Since the screening, identification and discrimination tests contain an above-threshold fragrance concentrations, a negligible deviation from the results of the otherwise usual testing is to be expected. However, in this procedure it should be taken into account that this is associated with faster consumption of the sticks and reduces the shelf life / durability of the sticks.

A Sniffin’ Stick is sufficient to paint 1000 cellulose paper stripes. This method may affect the lifetime of the Sniffin’ Sticks because the best-before-date is based on contact less presentation. Lifetime investigations are ongoing and pending.

Threshold test

Unfortunately it is not possible to use this method with the threshold test. At this moment we do not have a corona safe solution for the Sniffin’ Sticks threshold tests. The Threshold-Test has not yet been validated, because a different protocol was used for the unassisted application. Therefor it remains to be seen whether the methods are comparable.
