How Puritan Is Responding to COVID-19 

As a leading manufacturer of COVID-19 testing supplies, Puritan is working virtually nonstop to produce and rush supplies to the testing and medical professionals who urgently need them. 

This tremendous surge in demand for COVID-19 swabs and transport systems has resulted in inventory and order delays for many of our products at this time. We appreciate your patience and thank you for your understanding during this extraordinary time.

What is Coronavirus (COVID-19)?

Coronavirus is a type of virus that causes respiratory illness, an infection of the airways and lungs. While COVID-19 is a new strain of coronavirus, it's part of the same family of coronaviruses that includes the common cold.

How to Collect a Swab Specimen for Testing COVID-19

  • For initial diagnostic testing for COVID-19, CDC recommends collecting and testing an upper respiratory specimen. Nasopharyngeal (NP) specimen is the preferred choice for swab-based COVID-19 testing. When collection of a nasopharyngeal swab is not possible, the following are acceptable alternatives. Here is a full list: 

    • Nasopharyngeal (NP) specimen collected by a healthcare professional (HCP)

    • Anterior nares (nasal swab) specimen collected by a HCP or by onsite or home self-collection (using a flocked, a round foam swab, or spun polyester swab)

    • Nasal mid-turbinate swab collected by a HCP or by a supervised onsite self-collection (using a flocked tapered swab)

    • Oropharyngeal (OP) specimen collected by a HCP

    • Nasopharyngeal wash/aspirate or nasal wash/aspirate (NW) specimen collected by a HCP 

  • Depending on how the platform used to test the specimen, some tests are designed to analyze a swab specimen directly, without the use of any media. Other platforms require the swabs to be placed immediately into a sterile transport tube containing 2-3mL of either UniTranz-RT® Universal Transport Systems, Opti-Swab® - Liquid Amies Transport Systems, or sterile saline solution.
  • For those patients with productive coughs, sputum samples might be collected and used for testing Sputum Medium 

Puritan’s UniTranz-RT® (Universal Transport Systems)

  • Puritan’s UniTranz-RT®  is intended for the collection and preservation of viruses (including COVID-19), chlamydia, mycoplasma, and ureaplasma specimens. Our kits ensure the safe transport of clinical specimens when immediate testing is not available. Used in viral antigen detection tests, PCR and rapid tests.

  • UniTranz-RT® meets the CDC’s interim guidelines for collecting, handling and testing clinical COVID-19 specimens from persons of interest. Our flock swabs are the ideal swab for nasopharyngeal and oropharyngeal specimen collection when 2019-nCoV is suspected.
