Haemoglobinometry in New Units

Quality control in routine haemoglobinometry.

An analysis of haemoglobin estimations in a routine laboratory shows that quality control methods based on mean values are unsatisfactory. The use of a cusum method together with control samples is a sensitive and convenient technique for the early discovery of minor deviations in results and it is not dependent on a stable population of patients.

Physiological Measurements NEW APPROACH TO HAEMOGLOBINOMETRY BASED ON REFLECTANCE PHOTOMETRY

This paper describes a new approach to haemoglobinometry based on reflectance photometry using pretreated cell strip. A disposable cell strip is designed to absorb standardised volume of blood from a finger prick without any volumetric measuring apparatus. Pretreatment of the cell oxidises haemoglobin to methaemoglobin, thereby eliminating the errors of Tallqvist's method. The behavior of blood...

International standard for haemoglobinometry.

Some problems in the history of haemoglobinometry (1878-1931).

THE COLORIMETRIC estimation of haemoglobin concentration by reference to a standard of diluted blood was introduced by Gowers in 1878 and, after modification by Haldane in 1901, was widely used until the 1960s. Haldane's "normal" standard was determined by measurement of a very small group of men in Belfast and subsequent work indicated apparent differences between this and the normal level in ...

New Trends and Procedures of Program Assessment for Academic Units

Some consider assessment in terms of a systematic way of gathering and evaluating information within educational system and particularly higher education. Since, the term ‘’assessment’’ refers and relates to administrative processes, this paper has shed light some consideration on how it can benefit the members of department and program. Program assessment ultimately emphasizes on direction for...
