Infectious illness, a diagnosis is a laboratory test performed to identify infectious diseases with the assistance of trained technicians and medical professionals. It is a diagnostic process where the infectious disease's causing organism is described and located. The sample of urine, blood, mucus or other bodily fluids is examined using various diagnostic techniques and tools to reveal details about the causative organism.

Diagnostic procedures are essential for identifying diseases and enhancing global health. Traditional methods for diagnosing infectious diseases need to be more accurate and time-consuming. As a result of this shortcoming, quick, precise, and portable point-of-care testing kits have begun to appear in the market for infectious disease diagnostics. POC testing offers immediate results and enables quicker identification of infectious diseases to present close to the patient's location. Multiple scientists are now developing multiplex point-of-care diagnostic devices.

The market is bifurcated into hepatitis, human immunodeficiency virus (HIV), chlamydia trachomatis genital infection and gonorrhea (CT/NG), hospital-acquired infections, human papillomavirus (HPV), tuberculosis (TB), and influenza. The hospital-acquired infections segment is the highest contributor to the market and is expected to grow at a CAGR of 5.33% during the forecast period. Nosocomially acquired infections that are not present or incubating at the time of admission to a hospital are known as hospital-acquired infections (HAI). Hospitals may contain an infection or toxin that can cause these infections. These infections include bloodstream infections linked to central lines, urinary tract infections related to catheters, surgical site infections, pneumonia linked to ventilators, pneumonia acquired in hospitals, and infections with Clostridium difficile. Furthermore, according to the World Ageing Report 2019, there were 703 million people in the world who were 65 or older in 2019. By 2050, this number is expected to double to 1.5 billion. The elderly population is particularly vulnerable to infectious diseases because they frequently visit hospitals and have weakened immune systems. The incidence of HAI is therefore anticipated to increase due to the growing geriatric population, driving the market.

The hepatitis segment is expanding due to elements like rising hepatitis cases, initiatives by public and private organizations, and product launches. One of the drivers of the market's expansion is the government's expanding initiatives. For instance, a framework for eliminating viral hepatitis as a threat to public health in the United States by 2030 is provided by the Viral Hepatitis National Strategic Plan for the United States: A Roadmap to Elimination 2021–2025 (Viral Hepatitis Plan or Plan), which was published on January 7, 2021. The three most prevalent hepatitis viruses, hepatitis A, hepatitis B, and hepatitis C, that have the greatest effect on the country's health are the focus of the viral hepatitis plan.
