Result format:

R1:HDA (1,6-hexamethylene diamine): (µg/g creatinine)
R2: 2,4-TDA (toluene diamine-2,4): (µg/L)
R3:   2,6-TDA (toluene diamine-2,6) (µg/L) 
R4: MDA (4,4-methylene dianiline)  (µg/L)  

Reference values:

People exposed to HDI (hexamethylene diisocyanate 1,6)

Indicative biological limit value at the end of the workday
     
HDA (1,6-hexamethylene diamine): 17.5 to 52.6 µg/g creatinine
     
People exposed to TDI (toluene diisocyanate)

Indicative biological limit value at the end of the workday
     

2,4-TDA (toluene diamine-2,4): Less than 9.6 µg/L
2,6-TDA (toluene diamine-2,6): Less than 16.6 µg/L
     
People exposed to MDI (4,4-methylene diphenylisocyanate)biological limit value (BLW-DFG) at the end of the workday
     
MDA (4,4-methylene dianiline): 10.0 µg/L
     
Amines are analyzed metabolites appear in the urine of people exposed to the corresponding diisocyanate (HDI, TDI, MDI).
     
The relationship between urinary concentration of HDA and TDA and health effects is not established, so these values are only useful as indicators of level of exposure.
