Microhematocrit tubes are read according to PCV (Packed Cell Volume).
After centrifuging the tube, you will need a PCV card reader to determine the amount of packed red blood cells within the sample of blood. The PCV is determined by aligning the top of the clay plug (just as it reaches the layer of red blood cells) on the zero line and then gently "rolling" the tube up the chart until the intersecting middle line is aligned where the packed red cells and Buffy coat meet. Read across the chart and you should have a percentage of red blood cells to record as a PCV.

The speed and time of the centrifuge directly affect the microhematocrit values. Errors can be caused if it is not spun at the correct speed.

Best advice is to read the instructions on the tube or container

NORMAL MICRO HAEMATOCRIT VALUESmales : 0.40 - 0.50females : 0.37 - 0.43child : 0.38 - 0.44infants : 0.35 - 0.40new born : 0.50 - 0.58
The "normal" PCV count for males is 48% and 38% for women. The count does not vary for changes in body mass.
The Ampulla -Its the widest, longest portion of tube, it is usually the site of fertilization..(just read over this in my college anatomy class)..
