Do I need to pay for the shipment of the samples?

Shipping costs of the PT items to the participants are included in the price of the Schemes, with the exception of the Viable PBMC Scheme for which the 2021 pricing excludes the shipping costs for new participants. IBBL will take care of all the necessary documentation for shipment and customs. Nevertheless, for some countries, an import license is required to receive biological samples. In such cases, the Participant has to apply himself to obtain this import permit. Once the application is complete, the Participant provides the references of his/her import permit to IBBL.

When will my samples be shipped?

Once your registration is confirmed, your samples will be shipped to your location (at the exact address entered during the registration). You will be informed when the packages are shipped and an estimated date of delivery will be provided to you.

What do I do if my samples do not arrive?

If the shipment has not been received by the day after the estimated date of delivery, please contact immediately.

Can I get replacement samples?

Replacement samples are available only when samples have been received in an unsatisfactory condition (broken, leaking, received at incorrect temperature).
Replacement samples will not be provided if inappropriate manipulation or measurements have been done.

How do I test the samples and how do I dispose of them?

You should use your routine method(s) and apply your routine conditions to test/process the samples. IBBL will not provide direction as to the method or equipment to be used. Once tested/processed, samples should be discarded by following the safety instructions enclosed in the shipment in the Test Item Information Sheet or in the Processing Item Information Sheet.

How and when do I submit my results?

Results of your Proficiency Testing Schemes must be submitted online on the PT website ( Your login information (Laboratory Number and Password) will be sent to you by email after your registration.
Failure to submit your results by the deadline will result in the inability of IBBL to provide you with your PT Report and Evaluation of Performance.

How and when will I receive my Proficiency Test Report?

Your Scheme-specific PT Report(s) will be sent electronically by the end of February, at the latest.

Will I receive a Certificate?
