In-Office Diagnostics

precise, fast, family-focused

At Healthy Children Pediatrics, we believe that timely, accurate diagnostics are the foundation of great pediatric care. Dr. Raghunandan Sundaram, MD, FAAP offers a wide range of in-office diagnostic services so your child is evaluated, tested, and on the path to feeling better — all in one convenient visit.

Our goal is to minimize the burden on your family by bringing as many essential services as possible directly to you, with same-visit results, evidence-based guidance, and a treatment plan you can start the same day.

Pulmonary Function Testing (PFT) & Spirometry

Breathing problems in children deserve prompt, precise evaluation. Our in-office pulmonary function testing gives Dr. Sundaram the information he needs to diagnose and manage respiratory conditions accurately.

  • Performed in-office for children ages 5 and older
  • Measures lung capacity, airflow, and breathing efficiency
  • Used to diagnose and monitor asthma, chronic cough, recurrent wheezing, and other respiratory conditions
  • Helps determine whether current asthma medications are working effectively
  • Results reviewed with families immediately so a treatment plan can begin the same visit

Nebulizer Demonstration & Treatment

Navigating a new asthma or breathing diagnosis can feel overwhelming. Dr. Sundaram and our team are here to make sure your family feels fully prepared and confident every step of the way.

  • In-office nebulizer treatments administered during sick visits for children with wheezing or acute asthma flares
  • Hands-on nebulizer training provided for families of children newly diagnosed with asthma or reactive airway disease
  • Step-by-step instruction on proper technique, cleaning, and medication use at home
  • Spacer and inhaler technique demonstration also available
  • Ensures safe, effective respiratory treatment both in the office and at home

Respiratory Swab Testing

When your child is sick with a respiratory illness, knowing exactly what is causing it makes all the difference. Our comprehensive in-office respiratory swab testing takes the guesswork out of diagnosis.

  • COVID-19 rapid antigen and PCR testing
  • Influenza A & B testing
  • RSV (Respiratory Syncytial Virus) testing
  • Extended respiratory panel for parainfluenza, adenovirus, human metapneumovirus, Mycoplasma pneumoniae, and more
  • Same-visit results in most cases — Dr. Sundaram can begin targeted treatment right away
  • Reduces unnecessary antibiotic use by identifying viral versus bacterial causes
  • No outside lab visit required for most respiratory illnesses

Rapid Strep Testing

A sore throat should never mean a long wait for answers. Our rapid in-office strep test gets results fast so your child can start feeling better sooner.

  • In-office rapid Group A Streptococcus (strep throat) testing
  • Results available within minutes
  • Allows Dr. Sundaram to diagnose and prescribe treatment the same visit when appropriate
  • Prevents complications from untreated strep, including rheumatic fever and kidney problems
  • No outside lab visit required

Hearing Screening

Hearing is essential for your child’s speech, language, and learning. Routine in-office hearing screening helps catch problems early, when intervention is most effective.

  • Performed as part of every well-child visit in accordance with AAP guidelines
  • Screens for both conductive and sensorineural hearing loss
  • Newborn hearing follow-up assessments available
  • Tympanometry to assess middle ear function and detect fluid or ear infections
  • Critical for identifying hearing loss that may impact speech development and academic performance
  • Children who do not pass their in-office screen are referred promptly to a trusted pediatric audiologist

Blood Work

Routine blood work is a vital part of monitoring your child’s health at key developmental stages. Dr. Sundaram offers in-office blood draws and finger-stick testing for a variety of essential screenings.

  • Lead toxicity screening at 12 and 24 months (and as needed based on risk)
  • Hemoglobin and anemia screening
  • Lipid panel and Hemoglobin A1C
  • Blood glucose testing
  • Thyroid function testing (TSH)
  • Complete metabolic panel and CBC when clinically indicated
  • Most results available within 24 hours
  • All findings personally reviewed with families by Dr. Sundaram, with a clear explanation of what the results mean for your child

Vaccinations

Immunizations are one of the most powerful tools we have to protect your child’s health. Dr. Sundaram is committed to keeping every child in his care up to date and protected.

  • All routine childhood and adolescent vaccines administered in-office
  • Follows the AAP and CDC immunization schedules
  • Seasonal flu vaccines available every fall
