Quality control in routine haemoglobinometry

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.

Methods of Routine Haemoglobinometry in Childhood: Evaluation of Copper Sulphate Densitometry.

A routine haemoglobin determination is generally recommended as part of the health supervision of infants and children. This is easily done in hospital settings or private practice, but is far more difficult in mass child health supervision among deprived populations. Standard haemoglobinometry methods such as photoelectric colorimetry are poorly adapted to such a purpose because of their expen...

Quality assurance and quality control in the routine molecular diagnostic laboratory for infectious diseases.

Molecular diagnostics has become one of the dominant platforms in clinical laboratory medicine. Technological improvements, from automated sample preparation to real time amplification technology, provide the possibility to develop and run assays for a growing number of clinical questions. However, quality assurance and quality control issues have often remained underdeveloped but are still cri...
