High Hemoglobin Hematocrit And Red Blood Cells – Although a high red blood cell count does not always indicate a health problem, in some cases it can also be a symptom of a disease or disorder.
Red blood cells (RBCs), also called erythrocytes, are cells that carry oxygen throughout the body. They are also one of the main components of blood. A high red blood cell (RBC) count means that the number of red blood cells in the bloodstream is higher than normal.

High Hemoglobin Hematocrit And Red Blood Cells
If you experience signs and symptoms of a condition that may involve problems with the production of red blood cells, a complete blood count (CBC), which includes a red blood cell count, is usually ordered to help make the diagnosis. A complete blood count is usually part of the preoperative examination as well as routine physical examinations.

Changes in the number of red blood cells also mean changes in the levels of hemoglobin and hematocrit in the blood. When the red blood cell count, hemoglobin, and hematocrit are below the established normal range, the patient is said to be anemic. On the other hand, if a person has values that exceed the normal limit, he or she is said to be suffering from polycythemia. Too many red blood cells can lead to reduced blood flow and other related health problems, while too few red blood cells can significantly affect the amount of oxygen reaching the tissues.
Health care providers may order a CBC when patients exhibit some of the common signs and symptoms of anemia, such as:
This blood test may also be performed regularly to help monitor patients with certain blood disorders such as chronic anemia, bleeding problems and polycythemia, including kidney disease.
People undergoing cancer treatment also need to have regular blood counts because radiation therapy or chemotherapy usually reduces the production of all blood cells in the bone marrow.

Although a high red blood cell count does not always indicate a health problem, in some cases it can also be a symptom of a disease or disorder. Lifestyle and health factors can also cause an increase in red blood cell counts. Contain:
This rare blood disorder develops when the body produces too many red blood cells (RBCs). When red blood cells are overproduced, the blood becomes abnormally thicker, making people more susceptible to blood clots. The formation of blood clots can disrupt the normal flow of blood through veins and arteries and cause a heart attack or stroke.
Impaired blood flow also means that the body’s organs are deprived of the oxygen they need to function normally, which can lead to serious health problems such as angina and heart failure.
Back To The Basics: Blood Disorders
Polycythemia vera is a chronic blood disease that can be life-threatening if not properly diagnosed and treated. Although there is no cure for this disease, there are treatments that can help control the disease and its complications. Treatment for PV may also involve more than one treatment method to help control the disease.
The body tries to compensate and increase the production of red blood cells in case of any conditions that may cause low oxygen levels. These conditions include:
A malfunctioning kidney due to kidney disease, kidney transplant, and kidney cancer can cause the body to produce too much erythropoietin, which increases the production of red blood cells.
Some medications, such as methyldopa and gentamicin, may increase the number of red blood cells (RBCs). Methyldopa is a medicine used to treat hypertension (high blood pressure), and gentamicin is an antibacterial medicine used to treat bacterial infections of the blood. Be sure to tell your doctor about any medications you take.
Hematocrit (hct) Lab Values
When a person is dehydrated, the concentration of plasma, or the liquid component of blood, decreases and the concentration of red blood cells increases.
Your doctor may recommend certain medications or procedures to help lower your red blood cell count, especially if a medical condition is causing the abnormal count.
Your health care professional may perform a procedure called phlebotomy on a regular basis until your red blood cell (RBC) level is close to normal. During this procedure, a needle is inserted into a vein to collect blood into a designated container or bag.
For people with bone marrow disease or polycythemia vera, health care providers may prescribe hydroxyurea, an anticancer drug that can help slow the production of red blood cells in the body. While you are taking this medicine, you need to see your doctor regularly to monitor and make sure your red blood cell count does not drop too much to a dangerous level.
Rbc Blood Test: Normal Ranges And Diagnostic Uses
An elevated red blood cell count is usually found when doctors order blood tests to diagnose a patient’s condition. You can ask your doctor and discuss your blood test results. A high red blood cell (RBC) count and other abnormal test results are some indications that can help your doctor determine the cause of your condition.

Hematocrit (also written as hematocrit) is a measure of the volume of red blood cells in the blood, expressed as a percentage. In the laboratory, this can be determined manually by measuring the “volume of packed cells” or in an automated manner by determining the number of red blood cells and then multiplying it by the average cell volume (i.e. the fraction of red blood cell volume). Hematocrit can be estimated by tripling the measured hemoglobin concentration (in grams per deciliter or g/dL) and removing the units. Understanding Hematrocrit The term “hematrocrit” comes from the Greek words “haima” meaning “blood” and “krites” meaning “judge.” This word combination means “to separate the blood.” Hematocrit has the following additional names: Packed red blood cell volume (generally considered to be less accurate than measuring the erythrocyte volume fraction due to the plasma contained in the interstitial space of the packed cells) Packed red blood cell volume Erythrocyte volume fraction Effect Blood hematocrit on dried blood samples is an extensive topic of discussion. Hematocrit levels can vary depending on many factors that affect red blood cells. Your hydration level can affect your hematocrit. As the volume of water in the body decreases, the percentage of red blood cells increases. Additionally, studies indicate that arterial blood has a slightly lower hematocrit than venous blood. Why does this matter? Blood viscosity can alter the results of dry blood stain (DBS) paper or cards because viscosity determines how far the blood spreads on the dried blood stain paper. The sample spot area typically has a linear, inverse relationship with the blood hematocrit. Therefore, blood with a high hematocrit level results in a smaller dried blood sample; a lower hematocrit value results in a larger dried blood sample. The properties of the paper substrate can also affect how the blood sample spreads. It is known that the blood hematocrit effect (or hematocrit error) greatly affects the reliability and quality of data. If blood is distributed unevenly on the sample card, the area punched for analysis may vary despite the common assumption that punches of the same size contain the same amount of blood. Furthermore, the blood cells themselves may cause differences in the amount of analyte extracted from the surface of the DBS card itself. How to solve the problem of volumetric hematocrit deviation Whole-spot analysis, perforated and pre-cut DBS (PDBS) Whole-spot analysis is a way to avoid variability due to heterogeneity and different rates of blood spread due to hematocrit levels. Typically, the entire blood spot is cut from the paper, although this method of analysis has evolved towards perforated and precut DBS methods. With perforated DBS, the area of the card is determined and the blood is confined to that area, which is then cut from the card for analysis. With precut DBS, discs are precut from DBS paper and blood is drawn directly onto the disc, eliminating the hematocrit effect. Volumetric absorption microsampling The volumetric absorption microsampling technique involves immersing an absorbent tip of a size enabling the collection of a specific volume in a drop of blood. After a few seconds, the tip is filled with blood at an exact volume (e.g. 20 µl) with a deviation of less than 4%. The entire sample collected on the absorbent tip is then dried, extracted and analyzed. Because the entire tip is sampled, it is analogous to whole spot analysis in DBS, with the added benefits of more convenient sample collection and a simpler, automated workflow. Studies have shown that VAMS® effectively eliminates the hematocrit effect. Visit our library and check out published research
