I would like to participate in the CF EQA scheme for the first time, how should I proceed?

It is important to rule out any previous participation or any accounts created for your laboratory before. If you suspect this, please contact the CF Network by e-mail (). The CF Network will send you the account details of your laboratory if they exist yet.

In case this is indeed the first time your laboratory will participate, create an account first. There is a link named ‘new participant’ on the homepage, to a form which should be filled out. As soon as this form is filled out and submitted, your laboratory details are in the CF Network database. When the registration period opens, you will receive an invitation to register via e-mail. In case you create an account during the registration period, you will have immediately access to that registration form as soon as you receive your password and username via e-mail.

To find the registration form, go to the CF Network website, log in with your new username and password. You automatically arrive in the EQA participant’s area where you will find the link to the registration form.

How many samples are sent out for the CF EQA scheme?

Every year three DNA samples are sent to the registered laboratories end of January. All samples are accompanied with a mock clinical case.

What type of samples is sent for the CF EQA scheme?

The registered laboratories will receive three DNA samples. The samples were extracted by the salting out procedure from permanent cell lines, derived from leukocytes from patients or carriers of CFTR mutations. They were diluted to a concentration of 1µg/3µl (total 15 µl).

Which assay can I use to analyze the samples for the CF EQA scheme?

What is an EQA ID?

The numbers are assigned automatically when submitting the registration form. Each year the numbers change. Laboratories are strongly advised to use this number in all communication and on reports and raw data.

Who can participate in the CF EQA scheme?

The CF Network EQA scheme is open to all laboratories, public and private sector, that perform tests for cystic fibrosis. Companies offering CF kits are welcome as well to participate.

It is allowed to participate in the CF EQA scheme and only report genotypes. The genotypes will be assessed. However the certificate will mention that participation was unsuccessful because of the lack of interpretation.

Can I see my registration form once it is submitted?
