Notes

• In this calculator, mcg is the abbreviation for micrograms.

 
Equations used
 

Kt/VDaugirdas = -ln((BUNPost / BUNPre) - (0.008 * Hours)) + ((4 - (3.5 * BUNPost / BUNPre)) * UFVol / WeightPost)

Kt/VLowrie = ln( BUNPre / BUNPost)

Kt/VKeshaviah = 1.162 * ln( BUNPre / BUNPost)

Kt/VBarth = 3.1 * ((BUNPre - BUNPost) / BUNPre) - 0.66

Kt/VBasile = 2.3 * ((BUNPre - BUNPost) / BUNPre) - 0.284

Kt/VJindal = 4 * ((BUNPre - BUNPost) / BUNPre) - 1.2

Kt/VKerr = 4.2 * ((BUNPre - BUNPost) / BUNPre) - 1.48
