I am not. Rapid NAAT Tests through ID NOW are available at select Walgreens in the United States. On the website it says 1-2 days, but it actually takes 1-2 hours. NAT stands for Nucleic Acid Test. NAAT stands for Nucleic Acid Amplification Test. Both look for the Virus RNA rather than Antigens. Antigen Tests can be as fast as 15 minutes, but they have a higher rate of False Negatives. Please look at the Wikipedia Article for NAT where PCR is listed as a method of amplification. Please also look at the timing of the ID NOW Rapid NAAT Test which took 26 minutes at Walgreens. Please also look at the CBSA Website where NATs and NAATs are listed as separate from PCRs.

Yes both PCR and NAT / NAATs are completely different from Antigen Tests, but there are differences between PCR and NAT / NAATs, which I stated...
