Presence of serum 2 3 7 8-TCDD (serum dioxin)

Diabetes mellitus - Presence of serum 2 3 7 8-TCDD (serum dioxin) Factor

Serum 2,3,7,8-TCDD is defined by the RMA as meaning "2,3,7,8-tetrachlorodibenzo-para-dioxin as measured from an appropriately derived blood sample".

Note: Testing is no longer required to measure serum dioxin levels after changes to these factors in the SOPs issued on 13 July 2011. The new factors only require inhaling, ingesting or having cutaneous contact with the chemical agent over specified time frames. There are now also clinical worsening factors available.

Requirements for RH SOP are now:

inhaling, ingesting or having cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD),

• for a cumulative period of at least 500 hours,
• within a consecutive period of ten years
• before the clinical onset or clinical worsening of diabetes mellitus, and
• where the first exposure occurred at least five years before the clinical onset of diabetes mellitus, and
• where that exposure has ceased, the clinical onset or clinical worsening of diabetes mellitus occurred within 25 years of cessation.

Requirements for BOP SOP are now:

• inhaling, ingesting or having cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD),
• for a cumulative period of at least 1000 hours,
• within a consecutive period of ten years
• before the clinical onset or clinical worsening of diabetes mellitus, and
• where the first exposure occurred at least five years before the clinical onset of diabetes mellitus, and
• where that exposure has ceased, the clinical onset or clinical worsening of diabetes mellitus occurred within 25 years of cessation.

Note: The Rulebase has not been updated to reflect these changes as yet, so you may need to use the override or 'make' facility to record your decision if a new factor applies in the case you are assessing.
