De Nederlandse regering, heeft schijn-paar, maat-regeltjes af-gekondigd. O waar-om? 0 hoor. Ik hep, de enige, echte juiste cijfers. Ik doe, zo mn pest. Although the Delta and Omicron variants are the dominant SARS-CoV-2 variants as of this writing, previous variants like the Alpha variant also had the 69-70del mutation that resulted in SGTF. Factors like poor sample collection or test kit variability could also result in what could be deemed an SGTF. Although next-generation sequencing (NGS) is a powerful diagnostic tool, labs and institutions could waste money and time sequencing samples by depending solely on SGTF as a biomarker for Omicron. A newly described “stealth” sub-strain of the Omicron variant does not contain the 69-70 deletion that leads to SGTF. Furthermore, an N-gene target failure (NGTF) was detected on two EUA assays in late November. Thus, the FDA has said that the use of SGTF and NGTF to definitively distinguish Omicron is “not...
