Infectious diseases

A better plan starts with more insight

When a patient has a complex or chronic infection, care planning often requires convenient, easy specimen collection, comprehensive testing, and extensive support. With flexible tests and screens for a wide range of diseases, Quest Diagnostics provides you the actionable insights that help you provide the best care possible.

From hepatitis and tuberculosis (TB) to human immunodeficiency virus (HIV), tick-borne disease, and other infections, our testing menu is both diverse and innovative, accounting for resistant organisms and newly emerging strains of some of the most dangerous pathogens. You can also count on our suite of integrated services—including patient reminders and appointment scheduling—to optimize compliance during monitoring, treatment, and follow-up.

Adaptive testing programs emerge amid COVID-19

The pandemic exposed the challenges and opportunities in enabling faster and more effective diagnostics for infectious diseases. While vaccines have helped to significantly mitigate the transmission of COVID-19, new variants have proven to be particularly problematic among unvaccinated individuals and high-risk communities.

As these and other barriers take shape during the return to work, school, life, and healthcare, the need for comprehensive, flexible, and adaptive testing programs is evident. While COVID-19 has taken priority, the lessons learned from the pandemic also bring new insights for prevention, diagnosis, and management of future epidemics.

A comprehensive range of testing

Make more informed, confident diagnostic and treatment decisions relying on our extensive infectious disease test menu. Our quantitative and qualitative assays help physicians not only screen for and identify pathogens, but help in assessing treatment response and drug resistance, and in planning appropriate care.

Fight hepatitis with comprehensive A–E testing

In the United States, viral hepatitis cases continue to climb, disproportionately affecting younger patients and vulnerable communities. Many people are unaware of their infection, making screening even more vital. If left untreated, hepatitis can lead to adverse outcomes, from cirrhosis to liver cancer. Our extensive screening options, seamless results reporting, and clinical expertise are all designed to help you and your patients identify and manage hepatitis at every stage.

Assays for every stage of HIV

Our HIV-1 treatment and monitoring menu offers a full array of tests for determining HIV-1 subtype, assessing antiretroviral drug resistance, and selecting the appropriate treatment. With assays for all stages of disease, we help you support your patients throughout their care journey, from prevention and screening to monitoring treatments. 

The better way to test for TB

Screening for latent TB is important for many patient populations, including those initiating biologic/biosimilar therapy, migrant workers, healthcare personnel, and school-aged children, among others. The challenge is that standard skin screens can lead to false positives, lost time, and higher costs associated with follow-up testing. Choose the better way to test, especially in cases where latent TB may be suspected. Get insights only a blood test can yield—easily performed in one visit, with one tube.

An efficient path to the right diagnosis

For seasonal acute respiratory tract infections, timely clinical decision-making is crucial. Molecular respiratory syndromic panels from Quest Diagnostics provide accurate, rapid, reliable results so that you can start the appropriate treatment sooner while maintaining antibiotic stewardship.

All the tools you need in one place

Patients with vector-borne diseases can deteriorate quickly, but early detection mitigates complications. Quest Diagnostics offers convenient, one-visit screening solutions that can detect infections, including Lyme disease, Zika virus, malaria, and others, whether latent or not.
