The Nairobi Hospital laboratory – Eldoret Annex

Quality Control

Accuracy, precision and timeliness are vital characteristics of any good and progressive laboratory. The laboratory has state of the art equipment that analyses all blood and body fluid parameters. The division of laboratory is among few others in the country offering reliable and reproducible quality results. Forming an integral part of the Nairobi Hospital, the laboratory serves not only Kenyans but also those within the Central and Eastern Africa regions.

The department boasts of its quality through participation in numerous control programs both internal and external for each of the specialised areas.

The annex laboratories have elaborate quality control programmes, which involve in house daily quality control samples runs in all disciplines and constant regular checks with the mother laboratory in Nairobi.


The department functions ’round the clock’ throughout the year offering inpatient and outpatient testing capabilities, with an extremely comprehensive menu of investigations to choose from.
