A respiratory viral panel detects multiple common respiratory viruses from a nasal or throat swab. Typical targets include influenza A and B, respiratory syncytial virus (RSV), SARS‑CoV‑2, parainfluenza viruses, adenovirus, human metapneumovirus, rhinovirus/enterovirus, and seasonal coronaviruses. Some panels also test for less common viruses or include bacterial pathogens, depending on the laboratory’s test menu.

A multiplex test detects multiple pathogens or analytes at once from a single sample. It’s used in respiratory panels (SARS‑CoV‑2, influenza, RSV), gastrointestinal and sexually transmitted infection panels, and for genetic or biomarker targets. Multiplex assays speed diagnosis and help guide treatment by identifying which organisms or genetic markers are present in one run.

Costs vary by country and setting: in the U.S., a respiratory viral panel generally runs about $100–$500 out-of-pocket, though insurance often reduces the patient share. In countries with public health coverage it may be free to patients. In private labs elsewhere (for example, India) expect roughly ₹1,000–6,000. Check your provider or local lab for exact pricing.

A multiplex PCR test simultaneously detects and differentiates multiple pathogens or genetic targets in a single sample. It’s used for respiratory or gastrointestinal panels, sexually transmitted infection screening, and detecting antimicrobial resistance or outbreak strains. Multiplexing speeds diagnosis, improves sensitivity and specificity compared with single tests, guides targeted treatment and infection-control decisions, and reduces time and resources for comprehensive pathogen identification.

Costs vary widely. In the U.S. private labs typically charge about $100–$350 for a multiplex respiratory PCR panel; public insurance may cover it. In the U.K. it’s usually provided free through the public health system, while private testing can cost about £100–£250. In India private lab prices range roughly ₹1,500–8,000. Final price depends on included pathogens, method, and lab.

The most common respiratory infection is the common cold, an acute viral upper respiratory infection most often caused by rhinoviruses. It spreads easily by droplets and contact, causing runny or stuffy nose, sore throat, cough, sneezing, and mild fever. Symptoms usually resolve within 7 to 10 days; care focuses on rest, fluids, symptomatic relief, and good hand hygiene to prevent spread.
