62401-5

LOINC code 62401-5 identifies "PhenX - deep venous thrombosis protocol 041201". A screening question is asked about whether a person has been told that they have deep venous thrombosis (DVT) or blood clots in their legs. If the response is "yes," then two questions are asked about treatment for the condition. The third protocol provides a method to improve documentation of the condition by abstracting additional information from the person's medical record about the history and laboratory findings of DVT. If the respondent answers "no" or "don't know" to question 1, the protocol is complete. If the respondent answers "yes," continue with the protocol. This protocol refers to diagnoses during the subject's lifetime. For users wishing to collect longitudinal data, the question could be asked in relation to a previous study visit.

This code measures PhenX - deep venous thrombosis protocol 041201 in ^Patient. It belongs to the PANEL.PHENX class in the LOINC classification.
