FAQ
Type 3 sleep study — common questions
How much is a Type 3 sleep study at Soma Wellness Prime?
฿2,900. This includes interpretation and a consultation with a physician at Ittichai Clinic and a medical certificate. If the doctor recommends CPAP, a trial can start right away: ฿25,000 deposit and ฿2,000 per week, with the final week's fee waived if you buy your CPAP from Soma.
What is a Type 3 sleep study, and how is it different from a hospital (Type 1) study?
A Type 3 study is a one-night home test that records at least four signals: airflow, breathing effort, blood oxygen, heart rate and body position. The 2025 Thai clinical practice guideline accepts it for diagnosing moderate-to-severe OSA in people without complex comorbidities. A Type 1 study is done overnight in a hospital sleep lab with a technician present and also records brain waves.
How does the home test work?
We deliver the device and show you how to set it up (see the demo video on this page). Before bed you put on the chest belt, nasal airflow cannula and finger oximeter, sleep as usual, then remove it in the morning and return it. You can also be tested at Ittichai Clinic.
Who reads the results, and how long does it take?
A physician at Ittichai Clinic, a licensed medical clinic in Bangkok, interprets the recording, calculates your AHI using AASM criteria, consults with you and issues a medical certificate — in as little as 3 days.
What can the medical certificate be used for?
It can support a CPAP purchase and health-insurance or reimbursement claims, depending on your policy or coverage terms.
Who should not have a Type 3 study?
People with heart failure, COPD, stroke, neuromuscular disease, severe obesity with possible hypoventilation, or long-term opioid use should have an in-lab Type 1 study instead. The doctor will advise and refer you.
Do I need a sleep study before buying a CPAP?
Yes, it is recommended. Clinical guidelines call for diagnosing OSA and grading its severity before treatment, and the results help the doctor choose the right device and pressure settings.
Start Here
Take the STOP-Bang OSA Screening Questionnaire
8 questions, about 1 minute — find out whether a Type 3 sleep study is recommended for you
Question 1 of 8
SDo you snore loudly?
Snoring louder than normal conversation, or audible through a closed door
TDo you often feel tired or sleepy during the daytime?
For example: drowsy after meals, falling asleep watching TV or in meetings, needing daily naps
OHas anyone observed you stop breathing, choke, or gasp during sleep?
e.g., a bed partner, family member, or roommate has mentioned witnessed apnea
PDo you have or are you being treated for high blood pressure?
Including taking BP medication or having been diagnosed by a physician
BEnter your weight and height to calculate BMI
BMI above 35 kg/m² is a risk factor (calculated automatically)
AWhat is your age?
Age above 50 is a significant OSA risk factor
NIs your neck circumference greater than 40 cm (16 in)?
Measure at the larynx, or check whether your collar size exceeds 16
GWhat is your biological gender?
Biological sex assigned at birth — a STOP-Bang risk factor
Important: If anyone has ever witnessed you stop breathing or gasp during sleep (witnessed apnea), a Type 3 study with physician evaluation is recommended — regardless of your total STOP-Bang score.
📌 About the STOP-Bang questionnaire
STOP-Bang is a screening tool, not a medical diagnosis. It has high sensitivity (about 88–93%) but lower specificity (about 35–42%), so it should be used together with clinical history, physical examination and other findings.
Under the 2025 guidelines of the Thai Sleep Apnea Society and the Royal College of Otolaryngologists of Thailand, a score of 3 or higher is considered high risk for OSA and a sleep study is recommended — the final diagnosis is made by a physician at Ittichai Clinic.
