Many of the health professionals are afraid of being infected during activities in a blood testing laboratory. Is there any possibility of transmission during blood testing?
In a laboratory, there is no possibility of transmission through droplets/microdroplets. Anyone who practices universal precautions has no chance of being infected with SARS-CoV2.
Generally laboratory personnel are competent and trained to handle such testing. Accidentally they may contract infection. There are clear guidelines to handle infectious materials. If they follow these guidelines, the laboratory professionals have no fear of getting infection.
I would advice you to utilize your bio safety cabinet when manipulating any nasopharyngeal specimen, otherwise observe universal precautions when dealing with any bodily fluid in the laboratory. Laboratory management should provide further guidance on how personnel work during this uncertain time.
