    01.04.2020

    All COVID-19 tests should be performed in consultation with a health care practitioner and only in patients demonstrating symptomatic disease. Proper sampling is the key to accurate and correct laboratory test results!

    In addition to the most complete SARS-CoV-2 diagnostic portfolio, you can find up-to-date information, expertise and methodological assistance for each stage of the diagnostic process.

    Here's a quick guide to guidelines for collecting, manipulating and testing clinical samples from patients for coronavirus (COVID-19) recommended by the CDC!






    Guidelines for Collecting, Handling, and Testing Clinical Specimens from Persons for Coronavirus Disease 2019 (COVID-19)

    UPPER RESPIRATORY TRACKT

    • Nasopharyngeal swab (NP) / Оropharyngeal swab (OP)

    Use only synthetic fiber swabs with plastic shafts.

    NP swab: Insert a swab into the nostril parallel to the palate and swab over the surface of the posterior nasopharynx. Leave swab in place for several seconds to absorb secretions. Slowly remove swab while rotating it. Repeat the procedure for the other nostril.

    OP swab: Swab the posterior pharynx 3 times and withdraw the swab without touching the tongue and teeth.

    Place swabs immediately into sterile tubes containing 1-3mL of viral transport media, Amies transport medium or sterile saline.CDC is now recommending collecting only the NP swab. If both swabs are used, NP and OP specimens should be combined at collection into a single vial. OP swabs remain an acceptable specimen type.

    • Nasopharyngeal wash/aspirate or nasal aspirate

    Collect 2-3mL into a sterile, leak-proof, screw-cap sputum collection container.


    LOWER RESPIRATORY TRACKT

    • Bronchoalveolar lavage / Тracheal aspirate

    Collect 2-3mL into a sterile, leak-proof, screw-cap sputum collection container.

    • Sputum

    Have the patient rinse the mouth with water and then expectorate deep cough sputum directly into a sterile, leak-proof, screw-cap sputum collection container.


    STORAGE AND SHIPPING

    Store specimens at 2-8°C for up to 72 hours after collection. If a delay in testing or shipping is expected, store specimens at -70°C or below. Ship specimens overnight with ice pack or dry ice, according their storage temperature.

    Avoid freezing and defrosting the specimens.
