DASH Score Calculator (Tosetto 2012) — VTE Recurrence Risk
x402
DASH Score Calculator (Tosetto 2012) — VTE Recurrence Risk is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the Tosetto 2012 DASH score (D-dimer, Age, Sex, Hormonal therapy) for estimating venous thromboembolism recurrence risk after a first unprovoked VTE, returning the published recurrence risk band without percentages.

How this service works
Tosetto 2012 DASH (D-dimer, Age, Sex, Hormonal therapy) after a first unprovoked VTE: abnormal D-dimer after stopping anticoagulation +2, age <50 +1 (age 50 does not score), male +1, hormone use at the initial VTE in women -2. Score -2 to 4. Returns published recurrence bands <=1, 2, and >=3 without percents. Not a medical device and not a duration-of-anticoagulation order.
Output
Returns the computed DASH score (an integer from -2 to 4) and the corresponding published recurrence risk band (<=1, 2, or >=3), based on the Tosetto 2012 criteria. No percentage recurrence rates are included, consistent with the original publication. The result is informational only and not a clinical order or medical device output.
Example use cases
Post-anticoagulation VTE risk stratification
“My patient is a 38-year-old female who had a first unprovoked DVT. She stopped anticoagulation and her repeat D-dimer came back abnormal. She was on oral contraceptives when the VTE happened. Can you calculate her DASH score?”
Male patient unprovoked PE assessment
“I need the DASH score for a 55-year-old male who had an unprovoked PE. His D-dimer after stopping anticoagulants is normal and he was not on any hormonal therapy.”
Young female with VTE, no hormone use
“Calculate the Tosetto DASH score for a 29-year-old female with a first unprovoked VTE, abnormal D-dimer off anticoagulation, and no hormone use at the time of the event.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/dashWhen to prefer
Use this endpoint when you need to compute the validated Tosetto 2012 DASH score specifically for patients with a first unprovoked VTE who have completed a course of anticoagulation, and you need a structured risk band for clinical documentation or decision support workflow integration. Prefer this over manual calculation when building automated clinical pathways or EHR-integrated agents that require a reliable, versioned implementation of the DASH rule.
Side effects
- Missing required query parameters (age, sex, abnormal_d_dimer, hormone_use) returns a validation error
- hormone_use set to true when sex is male — schema violation
- age outside 18–120 range may return an error or undefined behavior
- Network or payment (x402) failure results in no score returned
