متن کاملImproved Quantitation of Cephalin-cholesterol Flocculation Test.
A rapid turbidimetric method for the determination of cephalin-cholesterol flocculation is described. Greater specificity and photometric sensitivity have been achieved along with adequate precision. The test is standardized with the conventionalbarium sulfate turbidity standards usedfor other laboratory procedures. Definition of results in turbidity units is proposed, and photometric standardi...
