This is our recommended protocol for blood smear examination: Scan the smear at low magnification, then use a higher magnification to perform a differential leukocyte count, enumerate nucleated RBC, estimate a platelet count, and evaluate red blood cell (RBC), white blood cell (WBC) and platelet morphologic features..
A health care professional will take a blood sample from a vein in your arm, using a small needle.
After the needle is inserted, a small amount of blood will be collected into a test tube or vial.
You may feel a little sting when the needle goes in or out.
This usually takes less than five minutes..
Erythrocyte count; Red blood cell count; Anemia - RBC count.
An RBC count is a blood test that measures how many red blood cells (RBCs) you have.
RBCs contain hemoglobin, a protein which carries oxygen.
How much oxygen your body tissues get depends on how many RBCs you have and how well they work..
Normal Results
Red blood cells (RBCs) normally are the same size and color and are a lighter color in the center.
The blood smear is considered normal if there is: Normal appearance of cells.
Normal white blood cell differential..
Introduction.
Erythrocytes, red blood cells (RBC), are the functional component of blood responsible for the transportation of gases and nutrients throughout the human body.
Their unique shape and composition allow for these specialized cells to carry out their essential functions..
Erythrocytes (red blood cells or RBCs) are anucleate, biconcave cells, filled with hemoglobin, that transport oxygen and carbon dioxide between the lungs and tissues.
They are produced in the red bone marrow by a process called erythropoiesis..
There are several potential causes of RBC in the urine, including:
In most cases, a doctor will discover RBC in the urine during a urinalysis.
A urinalysis checks for several key health indicators following the delivery of a urine sample.
Red blood cells (RBC) can be present in urine even when they are not visible to a person.
Also known as hematuria, RBC in urine can indicate an infection, kidney disease, and other health conditions.
Pregnant women should not see blood in their urine.
If they do, they should let their healthcare team know right away.
If they provide a urine sample with blood in it, a doctor will try to diagnose and treat any underlying conditions.
These inclusions are used to identify oxidant injury to red blood cells (Heinz bodies), immature red blood cells (basophilic stippling, Howell-Jolly bodies), lead toxicosis (basophilic stippling, siderocytes), and other conditions.
A very small amount of RBC may be present in a normal urine sample.
In fact, according to the Icahn School of Medicine at Mount Sinai in New York, the normal range for RBC in the urine is up to four RBC per high power field.
Eccentrocytes, pyknocytes and keratocytes:
