Abstract
At the end of 2019, in Wuhan, the Hubei Province's capital city in China, the first cases of COVID-19 disease caused by the novel coronavirus, SARS-CoV-2, were described. The rapid spread of the infection through the world resulted in the World Health Organization announcing the COVID-19 a global pandemic in March 2020. The main routes of transmission of the novel coronavirus SARS-CoV-2, according to current evidence, are via droplets inhalation, direct contact with contaminated surfaces, and transmission via the mucous membranes of the mouth, nose, and eyes, and probably through airborne particles from the respiratory tract, generated during coughing and sneezing of infected individuals. During the pulmonary function testing (PFTs), which require strenuous breathing maneuvers and generate high-intensity airflow, aerosols, and micro-aerosols are formed from respiratory secretions and may contain viral and bacterial particles. Therefore, such forced respiratory maneuvers pose a significant risk of spreading the infection to patients and laboratory staff. According to current knowledge, the source of infection may also be an asymptomatic and a pre-symptomatic individual. Coronavirus SARS-CoV-2 has been increasingly prevalent in the community, and this increases a potential risk to all patients tested lung function and staff working there. As the patients' and staff's safety is of unprecedented importance, the additional precautions when performing pulmonary function tests are necessary and unquestionable. In consequence, the greater availability of consumables and personal protective equipment is indispensable. The reorganization of daily practice will prolong test time, reduce the number of tests performed, and slow down patients' flow. The guidance provides practical advice to health care professionals on performing pulmonary function tests during the COVID-19 pandemic. It has been developed basing on currently available information and recommendations from relevant health care institutions. As the COVID-19 pandemic is a rapidly evolving situation and the new scientific data has been becoming are available, the guidance will be updated over time.

Summary
The first cases of COVID-19 disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were described at the end of 2019 in Wuhan, Hubei Province, China. — The ATS recommends that lung function tests can be performed after COVID-19 infection if the patient meets one of the following criteria: No fever (without the use of fever-reducing medications), resolution of respiratory symptoms, and two negative RT-PCR swab test results (taken ≥24 hours apart). — In patients who are vulnerable to severe consequences from SARS-CoV-2 infection, lung function tests should be carried out in a room with negative pressure ventilation and without air conditioning, if possible [29]. Organizational arrangements As the SARS-CoV-2 infection can be transmitted by droplet transmission and by contact with contaminated surfaces and contaminated air [6, 33, 35, 36], significant adjustments are necessary in both the technique of testing and in the organization of laboratories that perform respiratory function tests. It should not be used as a diagnostic tool instead of lung function testing [48]
