Laboratory examination of coronavirus disease in suspected human cases: interim guidance

Test	Type of sample	Timing
Nucleic Acid Amplification Tests (NAAT)	Upper respiratory specimens: nasopharyngeal and oropharyngeal swab nasopharyngeal wash/nasopharyngeal aspirate Lower respiratory specimens: sputum, endotracheal aspirate or bronchoalveolar lavage are preferred for patients with severe respiratory disease.	Upon introduction pick. Maybe repeated sampling to clearance monitor. Additional work is required to assess the repeated sampling is for efficient and accurate.
Serology and other	blood and stool are also responsible for the coronaviruses (COVID-19)	Paired samples are needed to confirm with the original sample obtained during disease of first week and the second one preferably obtained after 2–4 weeks (There has to be an ideal timing for convalescent samples Undertaken).

Upper respiratory specimens:

nasopharyngeal wash/nasopharyngeal

aspirate

Lower respiratory specimens:

aspirate or bronchoalveolar lavage are preferred for patients with severe respiratory disease.

Upon introduction pick. Maybe repeated sampling to clearance monitor. Additional work is required to assess the repeated sampling is for efficient and accurate.

Serology and other

blood and stool are also responsible for the coronaviruses (COVID-19)

Paired samples are needed to confirm with the original sample obtained during disease of first week and the second one preferably obtained after 2–4 weeks (There has to be an ideal timing for convalescent samples Undertaken).
