Performance Characteristics



  • Entire test performed in-house

Analytical Validity


This test detects >99% of described mutations


Not provided

Assay Limitation(s)


All coding sequences, including the flanking intron sequences are analyzed using direct sequencing. With this method we can detect point mutations and small deletions or insertions. The presence of larger deletions or insertions, or mutations outside the analyzed regions will not be detected.

PT Description
For Proficiency Testing, both external and internal, we have Sanger-sequenced extensive numbers of PCR fragments, and the error rate is less than 0.01% (99.99% accuracy). Technical specificity for methods used in our laboratory is estimated >99.5% and technical sensitivity >99.5%. Mutation detection reproducibility for Sanger sequencing is near to 100%.
