White Blood Cells: Frequently Asked Questions
What are WHITE BLOOD CELLS?
These are the principal components of the Immune System. They function by destroying foreign substances such as bacteria and viruses. Also known as leucocytes.

White blood cells are responsible for protecting the body from invasion by foreign substances such as bacteria and viruses. The majority of white blood cells are produced in the bone marrow, where they outnumber red blood cells by 2 to 1. However, in the blood stream, there are about 600 red blood cells for every white blood cell. There are several types of white blood cells. ...

White blood cells are an intricate system of defense mechanisms designed to block and destroy any foreign substance entering the body. White blood cells help fight infection, provide protection from foreign particles that enter the blood stream, such as allergens, and fight against mutated cells such as cancer.

Why are white blood cells relevant to the testing?
When the concentration of white blood cells (WBC) in the sample is greater than or equal to 1 million/ml, the seminal plasma will absorb light differently than when the WBC concentration is less than 1M/ml. Since light absorption is a critical element for determining sperm concentration, the user is required to select WBC “NORMAL” or “ABNORMAL” when testing a sample. Depending on the user’s selection, the SQA-V will use the appropriate algorithm to test the specimen.

How are white blood cells (WBC) measured in the sample?
What is relevant for accurate semen analysis readings using the SQA-V is to determine if the WBC concentration is GREATER than 1 million/ml. This can be measured by viewing the sample in the SQA-V visualization system or by using a QwikCheck™ Test Strips. These strips are labeled for the quantitative measurement of WBC’s in semen (and will also measure semen pH). Please click on the link below to view the User Guide Appendix: “Measuring WBC’s in Semen” for complete instructions on how to use test strips. ...

Does it cost more to have blood filtered to remove white blood cells?
Typically filtration adds 10% to 20% to the cost of preparing blood. The significant cost savings in hospital charges and reduced patient hospital stay associated with the use of filtered, leukocyte reduced blood and platelet transfusions, more than offsets the cost to leukocyte reduce by filtration. It has been estimated that for surgery patients alone the use of filtered blood would save the U.S. healthcare system six to twelve billion dollars per year.

What are white blood cells (WBC)?
WBC act as a primary defense line for the body against bacteria. Some types of WBC destroy invaders by engulfing them. Other types produce antibodies against protein antigens of foreign material.

Who can use the white blood cells?
The white blood cells stored are exclusively intended for use in the person from whom they were taken (or only for "autologous use"). They are a match for you.

How are white blood cells used in medicine?
Today, white blood cells are used in donor infusions, known as donor lymphocyte infusion. Donor lymphocyte infusion has mainly been used as a supplement for treatment to relapsed chronic myelogenous leukemia (CML), acute leukemia, chronic lymphocytic leukemia (CLL), myelodysplasia (MDS), Hodgkin's disease, non-Hodgkin lymphoma (NHL), and multiple myeloma. Donor lymphocyte infusions are also used to treat certain viral infections in transplant patients. ...

How are white blood cells different from stem cells?
Stem cells are master cells and have the capability to form into other types of specialized cells. Embryonic stem cells have been controversial but adult stem cell research has had much success. White blood cells originate from stem cells. Presently, peripheral blood white cells are not considered a significant source of stem cells. However, active research indicates it may be possible to isolate clinically significant numbers of them in the future.

What happens when the primitive stem cells begin to transform or differentiate into white blood cells in the host?
Primitive stem cells will produce any cell which your body communicates as being needed. However, stem cells also follow their own differentiation (transformation) programming and may produce white blood cells with HLA different to that of the hosts. In-house studies revealed that the small scale production of these cells inside the host creates an immunization effect similar to that of an allergy shot. The body becomes familiar with these cells in extremely small amounts. ...

Why would I want to save my white blood cells?
The single most important reason to bank your white blood cells is to preserve your future options. Because research is ongoing and new discoveries come about regularly, no one knows what the life-saving potential of white blood cells could be in the future. Currently, worldwide research directed at using white blood cells for treating cancer, genetic diseases and autoimmune diseases is being conducted. ...

Do, in any way, low white blood cells and low hemoglobin count lead to heart problems?
But it is ideal to have normal hemoglobin level to increase your exercise capacity.

How are white blood cells replenished?
A The white blood cells, of which there are 5 main types (neutrophils, eosinophils, basophils, monocytes, and lymphocytes), are central to immunity to infection. The first 4 types are constantly replenished by the bone marrow, where red blood cells and platelets are also made. Lymphocyte production is more complicated, and some of them emanate from lymph nodes. The spleen generally gobbles up old white blood cells after their short life span. ...
