In that case, the values quoted in the twoexamples would be 7.3 and 3.6 mmol/l, respectively.cThe reticulocyte concentration may also be reported in terms of the number concentration, i.e. the number per litre. In that case the column heading would read “reticulocyte no. concentration” and thevalues would depend on the erythrocyte number concentration (not reported in the examples given).d MEHC may also be reported in terms of the substance concentration; the column heading would then be “mean erythrocyte haemoglobin (Fe) concentration (MEH(Fe)C (mmol/l)”. In that case the examplequoted (no. 2) would have a value of 17.1.Table 2.6 Blood chemistry registerDate Specimen Patient Sent by Urea, substance Glucose concentration Other tests Results sentno. concentration (mmol/l) (mmol/l) (specify) (date)2.1.01 1 Mrs W Ward 1 12.8 — — 2.1.012.1.01 2 Mr G Dr W — 5.3 — 2.1.01Table 2.7 Urine analysis registerDate Specimen Patient Sent pH Direct microscopic Test for Test for Test for Test for Test for Chemical Other tests Resultsno. by examination glucose protein bile urobilinogen ketones test for (specify) sentpigments blood (date)2.1.01 1 Mr C Dr R 7.0 Leukocytes (20–30 Negative Negative ND ND ND ND ND 2.1.01per high-power field),few hyaline cysts2.1.01 2 Mrs E Dr A 6.8 Leukocytes (5–10 per +++ Negative ND ND + ND Pregnancy 2.1.01high-power field), few test: positiveepithelial cellsND: test not done; —: negative; +: weakly positive; ++: moderately positive; +++: strongly positive.
