Svarar mig själv, det var det inte men på SAS hemsida står det:
- Passengers entering or transiting through the USA must have a negative COVID-19 test taken at most 3 days before departure from the first embarkation point. Tests accepted are: antigen, NAAT, RT-LAMP, RT-PCR or TMA. Passengers details (e.g., name and date of birth) in the certificate must match those stated in the passport or other travel document; and the test result must specify "negative" or "not detected". If marked "invalid" it is not accepted.
