RESUMO
We collected morning urine samples from normal healthy persons, who had not yet breakfasted, in the age range of 2-61 years and measured urinary excretion of histamine and its metabolites N tau-methyl-histamine and N tau-methylimidazoleacetic acid. The values obtained (expressed in terms of urinary creatinine excretion), were age dependent up to the age of 12. Thereafter, values stabilized and were no longer age dependent.

The results of the analyses which were obtained with the Hemalog for the determination of platelets, white blood cells, red blood cells, hemoglobin and hematocrit were statistically analysed for the quality control of the determinations. Now that the testing method has been applied for 6 months, it appears from the results that it is extremely suitable for the determination of hemoglobin, red blood cells and the hematocrit and, to a lesser extent, for white blood cells and platelets.

The Hemalog system is an automated hematological instrument. From one sample this instrument determines the value for platelets (PBC), white blood cells (WBC), red blood cells (RBC), hemoglobin (Hb) and the hematocrit simultaneously. Moreover the system calculates the derived values: the mean cell volume (MCV), mean cell hemoglobin (MCH) and the mean cell hemoglobin concentration (MCHC). The values were investigated for cross sample contamination, coincidence, reproducibility, and compared with other methods. From this comparative study we can conclude that the Hemalog is a suitable and reliable instrument for hematological determination.
