Prices of the Qualitycheck Proficiency Testing

Prices of Participation

The final price of participation in interlaboratory proficiency testing organized by Qualitycheck depends on the number of measurands chosen. So every proficiency testing does not have a fixed price, but you pay only for parameters you need!

For example, an accredited laboratory for a total of 9 measurands (pH, conductivity and anions: fluoride, chloride, nitrite, bromide, nitrate, phosphate and sulphate) that wants to participate in the proficiency testing, named "Chemical and physical parameters in natural waters", which covers 19 measurands, can choose to be evaluated only for 9 measurands  paying a participation fee lower than the cost of the entire proficiency testing.

Advantages for the participating laboratories:

  • Saving on the cost of the participation in function of the number of measurands chosen.

  • Possibility to optimize participation in Proficiency Testing by choosing when and which measurands to evaluate, according to the internal needs of the laboratory (finance availability, availability of personnel, etc.) without increasing costs of participation so much.

  • In case of unsatisfactory results for some measurands (e.g. |z-score|>3), you can close the corrective actions, participating in further proficiency testing for only those measurands without having to pay full price.
