External quality assurance

Noklus provides external quality assurance (EQA) of pre-analytical and analytical work carried out in medical laboratories. Primary target groups are non-hospital laboratories. Our aim is to offer external assurance of all types of analysis that are commonly carried out in these laboratories. Large laboratories are also welcome to join. Additionally, we offer a special express delivery service to large laboratories if speedy delivery is essential and EQA programmes abroad cannot be used. If at all possible, we use patient-like materials and target values are established by a reference-method, or by calculations based on certified calibrators. Alternatively, we use method-specific target values. In addition to individual assurance, all scheme participants will be notified if Noklus discovers a systematic divergence between method median and a "true" value or if the lot numbers of the reagents employed generally show diverging results compared to the rest of the method group.

Noklus offers the following external controls:
Activated partial thromboplastin time (APTT), Cholesterol, C-reactive protein, D-dimer, Fecal occult blood (FOB), Fibrinogen, Glucose, Glycated hemoglobin (HbA1c), Helicobacter pylori, Hematology (cell count and differential count), Haemoglobin, Mononucleosis, Preanalytical survey, Pregnancy test, Prothrombin time (INR), Streptococcus A, Troponin T, Urine albumin and Urine albumin/creatinine ratio, Urine dip slide and Urine sticks (erythrocytes, glucose, leucocytes, nitrite, protein). 

In order to ensure that our controls are as patient-like as possible, Noklus produces large quantities of control materials based on freshly drawn blood and pools of human urine. Blood/urine from people with naturally high levels of the components included in the survey will be used whenever possible.

By taking part in the EQA programme, participants will receive:

  • Regular assessments for every EQA programme to which they contribute
  • An evaluation of their own results with feedback as to whether the results are consistent with those of others who employ the same method, and (if possible) if they equate with a "true" value. If diverging results may be caused by systematic divergence, whether linked to the method or the lot numbers used, this will be stated
  • Questionnaires relating to pre-analytical practice and feedback reports with details of their own results as well as aggregate data
  • Advice and guidance from our Noklus laboratory consultants if assistance is required in order to find and rectify any errors
