Pre-Employment Physical for Individuals
  • Be assured that you have a Physician doing your evaluation.
  • Some employers may require specific testing, therefore you will be asked to upload any paperwork for Dr. Sun to review prior to your appointment.
  • All physical exams you will be provided with an exam gown or shorts. Undergarments should be left on. If you arrive in your own shorts and loose fitting shirt, this may suffice and is up to Dr. Sun’s discretion.
  • Your Pre-Employment Physical will include:
    • Health Questionairre (fill out prior to appointment)
    • Medical History
    • Review of Medications
    • Review of Allergies
    • Physical Exam
    • Grip Strength
    • Hearing Screen
    • Vision Screen
    • Height, Weight, BMI
What is Your Office Like?
  • You can expect a humble, small, modest, clean, no-frills office.  There is no administrative staff, nor medical assistants as Dr. Sun performs all her own work. Pictures are on the ‘How It Works‘ page.
  • As you can imagine, the cost to provide a brick-and-mortar location is expensive, then couple that with providing medical services, the equipment and regulations required – it sometimes can be out of reach.
  • If you have an in-clinic appointment, there will never be a waiting room full of people. Appointments are separated by a substantial amount of time.  When you arrive,  the time and clinic is blocked only for you.
  • Dr. Sun was able to create two physically separate suites within what was once fully occupied by a computer shop. Now the suite in the back is the computer repair shop (Suite D2) , and her medical office occupies (Suite D1). We went through ~8 months of work to make this happen with the City of LA and San Pedro.

What is a Respirator Medical Evaluation?
  • The most basic respirator  that many are now familiar due to Covid-19 with are ones such as the N95 but there are many other types.
  • OSHA (Occupational Safety and Health Administration) requires medical evaluation before any employee can event be fit-tested, or wear, a respirator.
  • Medical evaluation requires filling out a questionnaire which Dr. Sun will review and make determination based off of this.
  • This option is not offered on its own.
  • Available in employer package.
  • Available for individuals who also require Fit Testing or other services.
What is Respirator Fit Testing?
  • Available ~April 1, 2024
  • A Respirator such as an N95 is considered a tight-fitting respirator, meaning it should fit without any leaks.
  • After you have been medically cleared to wear a respirator, you then need to be fit tested to wear the appropriate fitting mask.
  • At this time, Qualitative Fit Testing is able to be performed. This is the most common method and typically used for half-mask respirators.
What is Spirometry?
  • In medicine, we use Spirometry to measure your lung performance and volumes.
  • It is considered a pulmonary function test and can be performed in a medical office environment.
  • We often use spirometry to help diagnose, confirm or monitor diseases that are considered “obstructive” such as asthma, COPD and other pulmonary diseases.
  • You will be oriented to what the expectations of the test are in-office. Generally though, you can expect us to ask you take a full deep breath in (inspiration) and then breathe out as hard and fast as you can into a specialized measuring device. With this inspiration and expiration we are able to measure some important indices we need to measure your lung function.
What is NIOSH Spirometry?
  • NIOSH (National Institute for Occupational Safety & Health) could be considered the research arm of OSHA (Occupational Safety & Health Administration).
  • OSHA creates regulations for Employers and their Employees.
  • OSHA requires that employees exposed to certain materials such as cotton dust and cystalline silica (maritime, construction, mfg.) have spirometry tests and that these tests be administered by a Provider who is NIOSH Certified.
