Respiratory Infections

Respiratory tract infections range in severity from relatively mild infections, such as the common cold to potentially life-threatening infections, such as pneumonia. They are extremely common and are the leading cause of acute visits to the doctor’s office. While a specific diagnosis is not always necessary, reliable and timely diagnoses can be important in managing patient care.

The clinical presentation of patients with respiratory tract infections, particularly early in the disease course, often does not yield a specific diagnosis because the signs and symptoms are non-specific.

A Decisive Event For Respiratory Testing

The 2009 H1N1 influenza pandemic was a seminal event for respiratory virus testing. Studies showed that influenza rapid antigen detection tests had low sensitivities, ranging from 10-70%, for detecting the 2009 influenza A (H1N1) virus. Molecular testing, such as real-time PCR, became the preferred method for many because of its high sensitivity and fast turnaround time compared to standard viral culture.

We are committed to providing your laboratory with the products needed to meet your testing demands.
