I found this additional data on the Lepu ATK (ชุดตรวจโควิด ATK เล่อผู่):

[สสจ.เมืองคอนสั่งห้ามใช้ “ATK เล่อผู่” ในทุกโรงพยาบาล หลังพบผลตรวจมีความเบี่ยงเบนสูงมาก] https://mgronline.com/south/detail/9640000098465

Though the false positive error of the ATK is of concern in this news item, the result of the use of this ATK in other areas needs more careful considerations.

We need tools (Temperature Scan, self-diagnosis, mask, hand gel, soap, spray, distancing, lock-down, ATK, vaccines, …) to fight COVID-19 and we need to understand limitations of these tools. COVID-19 is not yet defeated.
