How do you look at blood under a microscope

Human blood contains many different components, from white blood cells to platelets, but the most abundant component by far are red blood cells. They serve an integral purpose: transporting oxygen from the lungs to all other parts of the body and returning carbon dioxide to the lungs to be exhaled. To accomplish this, they have a few unique features. In mammals, while developing red blood cells contain a nucleus and other organelles, before they mature fully, they extrude, or push out, these organelles. Having no nucleus, red blood cells are unable to create proteins or divide, but can they can store hemoglobin, the iron-containing molecule that binds oxygen and carbon dioxide.

How to observe red blood cells

Blood Microscopy is often associated with live blood cell analysis using dark field techniques. Proponents of this technique believe it readily provides information without the need to stain dead cells, while skeptics question its validity. This type of analysis is controversial and misused my many natural healthcare practitioners.

Presently, dark field blood microscopy is the only way to observe live blood cells. Practitioners take a small amount of blood from a patient, apply the sample to a slide and observe the blood. Most blood-microscopes come equipped with a camera and video equipment, allowing both the practitioner and patient to view the specimen together. In addition to red blood cells RBCs , white blood cells WBCs and plasma, blood microscopy is believed to show items within the plasma such as:.

Proponents of blood microscopy also claim to observe pleomorphic activity, the condition of major organs, mal-absorption of proteins, lipids and nutrients and immune system disorders. Commonly used synonyms for live blood analysis include:. Traditional observations require dried blood. A small sample is smeared onto a slide, stained and then observed under a microscope.

Staining allows transparent components such as erythrocytes and leukocytes to become visible. In addition, centrifugation can be used to separate components of blood for individual analysis.

Three common microscopic observation techniques are brightfield , dark field and phase contrast. Gunther Enderlein was first to describe using dark field for live blood analysis in the early s.

Dark field observations can produce artifacts, many of which were interpreted as disease-causing microbes by Enderlein.

He called them protits, symbionts or endobionts — organisms that can only be seen by live blood analysts. Enderlein and his followers believe that these organisms found in the plasma could transform into pathogenic agents and that their presence could predict future disease. Today, healthcare practitioners who utilize blood microscopy in-office connect these organisms with the need for vitamins, minerals and enzymes — products often conveniently sold at the office.

Some practitioners will administer the supplement and take another sample during the same visit, showing that the product has already begun to work. Live cell analysis can reveal traits of the blood samples such as the size and shape of cells. However, claims that blood microscopy can predict RBC coagulation, nutritional deficiencies and diagnose disease remains unproven. Scientific proof requires reliable results that can be reproduced by independent parties.

Presently, dark field blood microscopy fails to meet this minimum standard. A detailed report on the " Quack Watch " website reveals demonstrations of dark-field blood microscopy and raises questions regarding its validity. Many who administer live blood analysis tests make dubious health claims and manipulate test results to show a need for and subsequent proof that nutritional and enzymatic supplements are working.

Informal studies of live blood analysis show test results often cannot be replicated. Additionally, marked differences exist between the edge and center of the blood sample - the position of the microscope lens can result in different conclusions related to the same sample. Generally, those who employ in-office use of dark field blood analysis tend to be chiropractors, naturopaths and other holistic healthcare practitioners. Not approved by the FDA or covered by insurance, patients are required to pay out-of-pocket.

Infinity, a company that manufactures and holds demonstration on dark field microscopes for live blood analysis, states that practitioners should only use this instrument as an adjunct after taking a medical history and physical exam.

Nutritional recommendations should be reinforced by reviewing blood samples via video with patients, but not made based on the samples. Yet, if the practitioner is not supposed to point out nutritional deficits or make diagnosis based on the sample, merely identifying the basic components of blood has no apparent correlation with supplement and lifestyle recommendations. Dark field techniques allow for the viewing of live blood samples.

Utilized primarily by alternative healthcare practitioners, blood microscopy is not accepted as a valid technique by most doctors, researchers, insurance companies or the FDA.

The misuse of the technique, over zealous encouragement of patients to purchase supplements and the inability to independently repeat results make the diagnostic use of live blood analysis controversial.

Wrote the paper: JC. White blood cell WBC count is a valuable metric for assisting with diagnosis or prognosis of various diseases such as coronary heart disease, type 2 diabetes, or infection. Counting WBCs can be done either manually or automatically. Automatic methods are capable of counting a large number of cells to give a statistically more accurate reading of the WBC count of a sample, but the specialized equipment tends to be expensive. Manual methods are inexpensive since they only involve a conventional light microscope setup.

Blood Microscopy is often associated with live blood cell analysis using dark field techniques. Proponents of this technique believe it readily provides information without the need to stain dead cells, while skeptics question its validity.

A blood film —or peripheral blood smear —is a thin layer of blood smeared on a glass microscope slide and then stained in such a way as to allow the various blood cells to be examined microscopically. Blood films are examined in the investigation of hematological blood disorders and are routinely employed to look for blood parasites , such as those of malaria and filariasis. Blood films are made by placing a drop of blood on one end of a slide, and using a spreader slide to disperse the blood over the slide's length. The aim is to get a region, called a monolayer, where the cells are spaced far enough apart to be counted and differentiated. The monolayer is found in the "feathered edge" created by the spreader slide as it draws the blood forward.

Red blood cells also known as erythrocytes are responsible for carrying oxygen from the lungs to the rest of the body. Unlike other cells, red blood cells do not have a nucleus they have lost it during development. The available space can now be used to carry hemoglobin, the red pigment which carries oxygen. The red blood cells are disk shaped, with an indentation in the center. I accidentally cut my finger while preparing food. As an amateur microscopist, this is a fortunate opportunity to do yet another investigation. The cells can be observed in a wet mount. If you are interested in making a permanent mount, then the blood must be dried first.
