Nenänielunäyte

Nenänielunäyte refers to a sample collected from the nasopharynx, the uppermost part of the throat, behind the nose. This type of sample is commonly obtained using a nasopharyngeal swab. The swab is carefully inserted into one of the nostrils and guided towards the back of the throat to collect secretions.

The primary purpose of collecting a nenänielunäyte is for diagnostic testing. These tests can identify the presence of various respiratory pathogens, including viruses like influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19). It is also used to detect certain bacteria, such as *Streptococcus pneumoniae* and *Bordetella pertussis* (the cause of whooping cough).

The procedure is generally quick and well-tolerated, although it may cause a brief sensation of gagging or tickling. The collected sample is then sent to a laboratory for analysis using methods like polymerase chain reaction (PCR) or antigen testing to determine if specific pathogens are present. A positive result can help healthcare providers make an accurate diagnosis and initiate appropriate treatment or isolation measures. The nenänielunäyte is a valuable tool in public health surveillance and the management of infectious diseases.
