Regarding Albustix:
a. Useless if infected urine.
b. Gives red color.
c. Not useful if acid is added to urine.
d. Depends on acid precipitation of urinary proteins.
(c) Commercial strips for detecting albumin (Albustix) use the following formula:
Tetrabromophenol blue (yellow at 3.0) → shades of green in the presence of protein at the same pH.
This reaction is sensitive to 0.03g/L albumin. A false negative result occurs with acidification of urine. Also, a markedly alkaline urine (pH or higher can give false +ve.
