Bisulfite Binding Substances (B.B.S.) in the Blood and Cerebrospinal Fluid. ∗

Abstract

Conclusion

The amount of N/200 I₂ corresponding to the liberated bisulfite is equivalent to the total I₂ minus the thiosulfate. The value of the blank is then deducted from this figure. This difference is then multiplied by 3.67 for the blood sample and 2.75 for the spinal fluid sample. The result obtained equals the total B.B.S. expressed as mg of pyruvic acid per 100 cc.
