Interpretation Of Lab Results

Anemia, one of the more common blood disorders, occurs when the number of healthy red blood cells decreases in the body. The disc-shaped red blood cells contain hemoglobin, a unique molecule that carries oxygen to the body's tissues.   

                          The Blood A few nights working in a trauma center would tend to convince one that the body is just a huge bag of blood. In fact, an "average" 70 liter human body contains only about 5 liters of blood, or 7% by volume. In the normal state, blood has no business anywhere except in the confines of the heart and blood vessels and in the sinusoids of the marrow, liver, and spleen. Of the average 5 L of blood, only 2.25 L, or 45%, consists of cells. The rest is plasma, which itself consists of 93% water (by weight) and 7% solids (mostly proteins, the greatest proportion of which is albumin). Of the 2.25 L of cells, only 0.037 L (1.6%) are leukocytes. The entire circulating leukocyte population, if purified, would fit in a bartender's jigger. The total circulating platelet volume is even less -- about 0.0065 L -- or a little over one teaspoonful.

Complete Blood Count Test (CBC) What is the complete blood count test (CBC)?  Many blood tests measure the amount of a particular chemical or protein in your blood, but a complete blood count checks the blood cells themselves. It measures the numbers of different types of blood cells, their sizes, and their appearance. It is a very common and useful blood test. Any irregularities can then be observed and used as a basis for follow-up check-ups. In general, the test measures 3 main components of blood:

MICROSCOPIC URINALYSIS   Methodology A sample of well-mixed   urine (usually 10-15 ml) is centrifuged in a test tube at relatively low speed (about 2-3,000 rpm) for 5-10 minutes until a moderately cohesive button is produced at the bottom of the tube. The supernatant is decanted and a volume of 0.2 to 0.5 ml is left inside the tube. The sediment is resuspended in the remaining supernatant by flicking the bottom of the tube several times. A drop of resuspended sediment is poured onto a glass slide and coverslipped.
