I had use of the following: a binocular microscope with 100 oil and 10 low-dry objective lenses, two Neubauer hemacy-tometers, a microhematocrit centrifuge, a six-tube centrifuge for spinning urines, a battery-operated glucometer, an autoclave (my clinic "job description' included sterile processing), a number of stains, lots of different urine dipsticks, a 100-test slide pregnancy kit, and anything I could get from central supply (needles, gauze, alcohol, etc.

Red and white blood cell count was determined with chamber method using Neubauer's haemocytometer; haemoglobin concentration with cyanmethemoglobin method [13] and haematocrit in capillary tubes of 75 [micro]L volume, which were centrifuged in a microhematocrit centrifuge and the haematocrit values were read with a reader.
