Hemolysis is the premature breakdown of red blood cells (erythrocytes). It can lead to hemolytic anemia which happens when the bone marrow cannot compensate for the loss of erythrocytes. This condition can become life threatening.

A patient who has mild hemolysis may or may not have symptoms, depending on whether or not production rates of erythrocytes matches the loss.

Most disorders that lead to hemolysis are not race or sex specific. It can also occur at any age but in cases where it is hereditary, it usually begins at a young age.

Hemolysis is the bursting and destruction of red blood cells(erythrocytes) which causes the hemoglobin inside the cells to be liberated into the surrounding tissues. The blood cells may become hemolyzed by several different ways. If you had a sample of blood in a blood tube and shook it vigorously this would cause the cells to burst thereby ruining the blood specimen.

Other reasons the erythrocytes may become hemolysized include snake venoms, immune bodies, bacterial toxins, and hypotonic saline solutions.

Hemoglobin lost by hemolysis will turn the urine red, this is called hemoglobinuria. Hemolysis can also be visualised under the microscope.

Hemolysis is the process of breakdown of red blood cells in the blood.  In this process haemoglobin, the substance giving red colour to the blood, is released from the red cells.  Hemolysis is a normal body process in which about 0.8 of 1 per cent of all red cells in the body are broken down each day. 

Hemolysis is usually balanced by production of new red cell.  But, sometimes the rate of cell breakdown is higher than the capacity of body to produce new cells. This may result in anaemia. Chemical poisons may cause Excessive hemolysis may be caused by various reasons like poisoning or production of antibodies in the body affecting red blood cells.

Blood pressure is the force exerted by your blood against your arteries. As your heart pumps, it forces blood out through arteries that carry the blood throughout your body. The arteries keep tapering off in size until they become tiny vessels, called capillaries. At the capillary level, oxygen and nutrients are released from your blood and delivered to the organs. Blood pressure is measured with an instrument. First, a cuff is placed around your arm and inflated with a pump until the circulation is cut off. A small valve slowly deflates the cuff, and the doctor measuring blood pressure uses a stethoscope, placed over your arm, to listen for the sound of blood pulsing through the arteries. That first sound of rushing blood refers to the systolic blood pressure; once the sound fades, the second number indicates the diastolic pressure, the blood pressure of your heart at rest. More of this information can be exclusively found at this site.

Hemolysis is the breakage of the red blood cell’s (RBC’s) membrane, causing the release of the hemoglobin and other internal components into the surrounding fluid. Hemolysis is visually detected by showing a pink to red tinge in serum or plasma. An improper choice in the venipuncture site, such as drawing from a distal site to the antecubital region of the arm rather than drawing from an antecubital site, has been shown to result in more hemolysis. (Mainly all the information about this is valid and important in the article link given.)
