Targeted genotyping

DNA₁ looks beyond the most common alleles to identify cases involving NULL or rare variants that might otherwise be missed

Next-generation sequencing of the SERPINA1 gene

There are over 120 known variants to the SERPINA1 gene¹⁶
Sequencing of all exons, splice sites, and the promoter region of the SERPINA1 gene help you identify all Alpha-1 patients and carriers
DNA₁ provides full next-generation genetic sequencing of the SERPINA1 gene to identify known and previously undiscovered variants

Clinical chemistry

DNA₁ is the only available test that screens for both A₁AT protein levels and C-reactive protein (CRP) levels to give context to the A₁AT results and help prevent false negatives*

*CRP, like A₁AT, is an acute-phase protein, which means levels of it may be elevated with inflammation. This CRP test is not a high-sensitivity test; it is used as a measurement of inflammation.

Isoelectric focusing (IEF)

IEF phenotyping results serve as a confirmatory step for genotyping results, giving added confidence that results are accurate. With DNA₁, there is typically no need to retest

Accurate and Convenient Testing and Results

The DNA₁ Advanced Alpha-1 Screening Test Kit offers both accuracy and convenience when detecting Alpha-1, and there is no charge for the kit, lab processing, or lab results.

The AdvanceDx100 serum separator card simplifies test administration:

Only 1 blood spot (an average of 4 to 6 drops of blood) needed
30-minute drying time
Accurate and confident diagnosis without the need for additional testing
