Abstract:
The estimation of protein in cerebrospinal fluid (CSF) is important in certain disease conditions. The
sensitivity of the Biuret method which is the standard method for protein estimation is not sufficient to
be used for CSF specimens. This has lead to the development of various assay techniques for this
purpose. The laboratory of Teaching Hospital, Karapitiya employs two such methods; the Pyrogallol
red (PGR) method in the day laboratory and Sulphosalicylic acid turbidimetric method (SS A) in the oncall
laboratory. The aim of this study was to compare these two methods.
