12.4 Laboratory procedure book

If the laboratory is to continue operating after the departure of the laboratory technologist who initiated the activity, a set of notes giving the methods used in the laboratory, together with the addresses of local and national laboratory suppliers and a map showing their location, should be prepared. For reordering of basic stains and reagents, a record should be kept of usage rate of, for example, Field’s or Giemsa’s stains (e.g. 300-400 malaria smears a month required 1000 mL of Field’s A and 1000 mL of Field’s B).

It is important for epidemiological assessment that monthly statistics are compiled. Figures 12.5, 12.6 and 12.7 show how specific and summary monthly reports may be presented.
