How this service works
Chorin 2016 Roth score: caller max_count (integer 1-30, highest number reached counting 1 to 30 in one breath) and counting_time_seconds (greater than 0, at most 60). Echoes both; time to 1 decimal. Flags quote Table 2/discussion: max_count <10, counting_time <7 s, max_count <7, counting_time <5 s. Not a hypoxia class or 2021 general-practice cutoff. Not a medical device. magent does not time the patient.
Output
Returns the echoed max_count and counting_time_seconds (rounded to 1 decimal place), plus boolean flags for the four clinically notable thresholds from Chorin 2016 Table 2: max_count <10, counting_time <7 s, max_count <7, counting_time <5 s. Does not assign a hypoxia class or apply 2021 general-practice cutoffs.
Example use cases
Pre-op respiratory screening
“We just did a counting test on a pre-op patient — they reached 8 before running out of breath and the stopwatch read 6.2 seconds. Run the Roth score and tell me which Chorin 2016 thresholds are flagged.”
Telemedicine lung function check
“My patient counted to 15 over a telehealth call and it took 9.8 seconds. Can you compute the Roth score and let me know if any of the Table 2 flags apply?”
Documenting borderline counting test result
“Patient only got to 6 and the time was 4.5 seconds on the counting test — what does the Roth score calculation say and are the critical low thresholds triggered?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rothWhen to prefer
Use this endpoint when you need to apply the specific Chorin 2016 Roth score thresholds (Table 2 flags) to a completed counting test and want an authoritative, versioned clinical calculator. Do not use if you need a hypoxia classification, the 2021 general-practice Roth cutoffs, or if the patient has not yet performed the counting test — the endpoint does not administer or time the test itself.
Side effects
- max_count outside 1–30 range returns validation error
- counting_time_seconds ≤0 or >60 returns validation error
- Missing required parameters returns error
- Non-integer max_count returns schema validation error
