The US Food and Drug Administration has granted 510(k) clearance for QIAGEN’s ipsogen® JAK2 RGQ PCR Kit (ipsogen JAK2 assay), and the company has launched the assay in the US.
The ipsogen JAK2 assay is designed to detect the JAK2 V617F/G1849T allele in genomic DNA extracted from EDTA whole blood.
The assay is intended for use in conjunction with other clinicopathological factors to aid the diagnosis of polycythemia vera (PV).
The test does not detect less common mutations associated with PV, including mutations in exon 12, and is not intended for stand-alone diagnosis of PV.
The ipsogen JAK2 assay is a real-time polymerase chain reaction test performed on the QIAGEN Rotor-Gene Q MDx instrument.
Researchers evaluated the utility of the ipsogen JAK2 assay for PV diagnosis in a prospective trial enrolling more than 200 subjects.
Data from this trial have not been published. However, according to QIAGEN, the assay provided 94.6% sensitivity and 98.1% specificity, together with a 100% positive percentage agreement and a 99.4% negative percentage agreement to bi-directional sequencing.
QIAGEN said these results suggest the ipsogen JAK2 assay enables detection of PV in the majority of subjects with the disease and helps rule out PV in the majority of individuals without it.
“We are pleased to be able to offer our ipsogen JAK2 assay, which is already available in Europe and other markets, for use in the United States and make it easier for hematologists and oncologists to follow recommended diagnostic testing algorithms and international guidelines for suspected PV patients,” said Thierry Bernard, senior vice president and head of QIAGEN’s Molecular Diagnostics Business Area.
