Normal Rbc But Low Hemoglobin And Hematocrit
With so many different laboratory tests, it can be challenging to learn and remember standard values.
Hgb Blood Test: Why It’s Done And What It Can Show
We have compiled a list of simple methods to help you remember the normal laboratory levels of common blood tests.
This is a great review for nursing, NCLEX and USMLE as well as any student and professional in the medical field.
You will learn techniques to recall normal laboratory values for complete blood count (CBC), chemistry or basic metabolic panel (BMP), comprehensive metabolic panel (CMP), liver function test (LFT), arterial blood gas (ABG). and coagulation studies.
Let’s review the main components of BMP as well as ways to remember their common values.

There are usually 3-5 bananas in a pack, and you want to buy 1/2 off if you can.
Bunions are commonly found on the toes or digits and we have 5 digits on each end, making a total of 20 digits.
0.9 is right in the middle of normal, and this helps you remember the normal range of 0.6-1.2 mg/dL.
A comprehensive metabolic panel essentially includes a liver function panel/test (LFT) for everything in a basic metabolic panel.

Another way to think about AST is to use the 9am start time for school, and then the average school week is when you do about 40 hours of homework.
Just as we used “S” in AST to denote education, we are going to use “L” in ALT to denote labor.
An average workday is longer than a school day and can start at 7pm and end at 6pm.

Another way to think about ALT is to use the 7am start time for work, then the average work week would be 60 hours.
80 is right in the middle of normal, and this will help you remember the normal range of 40-120 U/L.
Normal hemoglobin for women is 12-16 g/dL, and normal hemoglobin for men is 14-18 g/dL.
When you think about hematocrit, think about hematocrisis and the crisis that occurs in midlife, which is usually around the age of 40-50.

The main components of ABG that help determine acid-base status include pH, PACO2, and HCO3 (bicarbonate).
We know the pH scale is 0-14, and we know the body likes to be in homeostasis.
Instead of “F” you can use “pH” to write the word “four” (4) with “pH”.
Since bi is 2, we multiply 12 by 2, which gives us 24.

Let’s Talk About Hematocrit Again!
Previous Previous Common Medical Abbreviations and Abbreviations Next Next Speech and Language Critical Issues for Children: NCLEX Chart, Nursing Mnemonic Hematocrit (HCT) refers to the amount of red blood cells (RBCs) in an individual’s blood. Adults with XY chromosomes usually have 40% to 54% HTT. have, and adults with XX chromosomes have an HCT of 36% to 48%. In addition to RBCs, blood has three other major components: white blood cells, platelets, and plasma.
Hematocrit measures the percentage of red blood cells in the total blood volume. Hematocrit testing can be done using a capillary tube and a centrifuge machine (that is, a machine that uses centrifugal force to separate blood components due to their different densities). Hematocrit levels are usually determined as part of a complete blood count (CBC), but they can be tested alone. However, CBC is a more common blood test that measures red blood cell count, white blood cell count, hemoglobin level, and HCT, which measures platelet count.
Hematocrit is a very important laboratory finding because having too few or too many RBCs can be a clinical sign of various medical conditions such as anemia or polycythemia. It can be used to monitor individuals after surgery to prevent or screen for complications such as internal bleeding.
Low hematocrit levels, also known as anemia, may be the result of decreased RBC production, increased bleeding, increased destruction of RBCs, or a combination of these.
Hemoglobin And Hematocrit
The most common cause of low hematocrit levels is chronic (eg, ulcer, colon cancer) or acute (eg, trauma, internal bleeding) bleeding, which leads to massive bleeding. In particular, individuals of reproductive age who are assigned to be female at birth may have a low hematocrit due to their menstruation. However, as seen in conditions such as sickle cell anemia, the hematocrit may decrease due to the short-term loss of RBCs. and splenomegaly (ie enlargement of the spleen), too many healthy RBCs are destroyed in the spleen. Another cause of low hematocrit is decreased production of RBCs, as seen in chronic inflammatory diseases, or bone marrow suppression due to radiation therapy, malignancies, or drugs such as chemotherapy. Finally, nutritional deficiencies (eg, iron, B12, and folate deficiencies) as well as overhydration can cause a decrease in hematocrit.
Dehydration can result in hemoconcentration due to fluid loss from repeated vomiting, overheating, or limited fluid intake. In addition, low oxygen supply causes the formation of new blood cells to transport oxygen in the body and can be caused by smoking; High altitudes: Congenital heart diseases or certain lung diseases such as pulmonary fibrosis or chronic obstructive pulmonary disease (COPD). In addition, polycythemia vera, characterized by overproduction of RBCs due to bone marrow stimulation (ie, myeloproliferation), can cause a high hematocrit. Similarly, increased erythropoietin production due to androgen use or erythropoietin production from the kidneys, liver, and ovaries also increases hematocrit. Finally, various disorders of the endocrine system, such as Cushing’s syndrome, can cause high hematocrit levels.
Hematocrit measures the percentage of red blood cells in the total blood volume. Many types of health problems and especially blood diseases can be diagnosed by hematocrit test. Low hematocrit levels, also known as anemia, can be the result of decreased RBC production, increased blood loss, increased destruction of RBCs, or a combination of the above. On the other hand, a high hematocrit can be a result of hemoconcentration or RBC overproduction, which can be caused by a variety of factors.

Polycythemia Or Too Many Red Blood Cells
Kragh-Hansen, U. (2018). Potential mechanisms by which enzymatic degradation of human serum albumin may lead to bioactive peptides and biomarkers. Frontiers in Molecular Biosciences, 5: 63. DOI: 10.3389/fmolb.2018.00063 Polycythemia (also known as polycythemia) is a laboratory finding of increased hematocrit (the percentage of red blood cells in the blood) and/or hemoglobin. in the blood. Polycythemia is sometimes called erythrocytosis, and there is a significant overlap in the two findings, but the terms are not the same: polycythemia describes an increase in hematocrit and / or hemoglobin, while erythrocytosis describes an increase in red blood cells, especially in the number of red blood cells. Blood.
Absolute polycythemia can be caused by genetic mutations in the bone marrow (“primary polycythemia”), physiological adaptations to a person’s viromet, drugs, and/or other medical conditions.
Laboratory studies, such as serum erythropoeitin levels and genetic testing, may be useful in clarifying the cause of polycythemia if physical examination and history of the patient do not reveal the cause.
Mild polycythemia itself often has no symptoms. Treatment for polycythemia varies, and typically involves treating the underlying cause.
A Guide To Anemia
Treatment of primary polycythemia (see polycythemia vera) may include phlebotomy, antiplatelet therapy to reduce the risk of blood clotting, and additional cytoreductive therapy to reduce the number of red blood cells produced in the bone marrow.
Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (Hgb) greater than the normal range for age and sex, typically Hct > 49% in healthy adult m and > 48% in women, or HgB > 16.5g/dL in m or > 16.0 in women. G / DL.
A variety of diseases or conditions can cause polycythemia in adults. These processes are explained in more detail in their sections below.
Relative polycythemia is not an increase in the number of red blood cells or hemoglobin in the blood, but a high laboratory finding due to reduced blood plasma (hypovolemia, cf. dehydration). Relative polycythemia is often caused by loss of body fluids, such as burns, dehydration and stress.

A specific relative type of polycythemia is Gaisbock syndrome.
