Respiratory Testing in NYC and Long Island

Respiratory testing

COVID-19, influenza and RSV can cause overlapping symptoms. A clinician may recommend a test for one virus or a multiplex test for several viruses when the result can guide treatment or other care. The examination also checks for breathing difficulty and causes that the test does not cover.

How respiratory testing works

Antigen tests detect viral proteins. Molecular tests detect genetic material and are generally more sensitive. A multiplex panel has a defined list of targets, not every respiratory infection. Finding one virus does not exclude another infection. A negative antigen result can miss an infection.

Eligibility: Respiratory testing

Testing can be useful for a symptomatic person, someone at risk of severe illness or a particular infection-control need. The right test depends on the patient's age, symptoms, time since onset and available assay. Not every mild illness needs a broad panel.

What to expect: Respiratory testing

Review symptom onset, exposure, medical conditions and current medicines. The clinician selects a test and sample type, then discusses whether treatment can start before the result. Flu and COVID-19 treatment may need prompt decisions in a person at increased risk.

Preparing for your appointment

Bring the symptom timeline, previous tests and medicine list. A nasal swab generally does not require fasting. Tell the team about illness before arrival. Follow instructions for the exact collection method rather than combining unapproved sample sites at home.

Risks and when to seek help

Severe breathing trouble, chest pain, confusion or blue lips requires emergency care. Infants with breathing pauses or poor feeding need urgent assessment. Do not use a negative panel to decide that serious symptoms are safe to ignore.

Follow-up and treatment review

Discuss what a positive or negative result means for treatment and follow-up. Persistent symptoms can need further examination, another test or evaluation for pneumonia or a noninfectious cause. Ask who will review send-out results.

Appointments, costs and coverage

Confirm which viruses the clinic's test detects, whether it is antigen or molecular, collection hours and expected results. A service-family listing does not prove every clinic uses the same panel. Ask about separate visit and laboratory charges.
