COVID-19 Direct Kit

Enabling Swift Action Against the COVID-19 Pandemic

KIT for Infectious Diseases



Coronaviruses (CoV) are a large family of viruses that cause illnesses ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV).1 The current outbreak of coronavirus disease was first reported from Wuhan, China in December 2019. After cases were identified in several countries, a global health emergency and then a pandemic were declared.2

Currently, the pandemic is evolving with high concern for possible SARS-CoV-2 variants in regards to their transmissibility and impact on current vaccines or available immunotherapy.3 Testing needs have also shifted throughout the pandemic as global shortages of supplies created unique issues for laboratories all over the globe.4

The Simplexa® COVID-19 Direct kit (EUA) allows for fast results directly from nasopharyngeal swab, nasal swab, bronchoalveolar lavage (BAL) and nasal wash/aspirate specimens, eliminating traditional RNA extraction steps. This enables faster turnaround times to help improve identification of positive individuals, patient management, allocation of critical resources and prevent further transmission of the disease.5,6

The Simplexa® COVID-19 Direct kit detects the presence of SARS-CoV-2 RNA, including the variants Alpha (B.1.1.7), Beta (B.1.351), Gamma (P1), Delta (B.1.617.2), Epsilon (B.1.427/B.1.429), Zeta (P.2), Eta (B.1.525), Iota (B.1.526), Kappa (B.1.617.1) and Lambda (C.37).7

Why to choose it

An easy to use sample to answer system – no extraction and all-in-one reagents. Comprehensive sample coverage including nasal swab, nasopharyngeal swab, nasal wash/aspirate, and BAL specimens to work with any workflow. The Simplexa® COVID-19 Direct assay and the Simplexa® Flu A/B & RSV Direct assay can be run on the same disc at the same time for differential diagnosis of SARS-CoV-2, Flu A, Flu B and RSV.


Highly Sensitive

Results You Can Depend On

The Simplexa® COVID-19 Direct assay targets two different regions of the SARS-CoV-2 genome to provide high sensitivity and help prevent false negatives.

Fast Results

Fast Time-to-Result

A simple workflow with minimal hands on time and results in a little more than an hour allows more efficient test reporting and patient management.

A Complete Solution

All You Need

The simplicity and flexibility of the LIASION® MDX system, combined with the broad sample coverage of the Simpexa® COVID-19 Direct assay design is a major step towards fighting the COVID-19 pandemic.
