Haemoglobin Lab Report

As the concentration of hemoglobin in the Red Blood Cells falls below normal, the total Red Blood Cell count consequently decreases. Therefore, oxygen cannot be adequately carried. (http://www.mayohealth.org/mayo/pted/htm/iron.htm).

People who have Myelodysplastic Syndrome may not experience symptoms at the beginning of the disease. However, there are three main signs that can develop and alert healthcare providers that something is wrong. One of these is a low red blood cell count, or Anemia. Most patients that have myelodysplastic syndromes exhibit this indicator when first diagnosed. A normal red blood count can vary between 4.0 and 6.1 million red blood cells per microliter of blood in the body, depending on the age and sex of the patient. A red blood cell count lower than normal is characteristic of Anemia (Cafasso, Jacquelyn, and Gotter). Not only is Anemia shown by constantly low hematocrit, but it can also be characterized by constantly low hemoglobin. A normal hemoglobin count is between 12.0 and 15.5 grams per deciliter of blood for females, and 13.5 to 17.5 grams per deciliter of blood for males. Levels lower than these show a low hemoglobin level (Mayo Clinic, Hemoglobin Test). Hemoglobin is the protein in blood that carries oxygen to the different tissues in the body.

Intraoperative ultrasonography has been used to determine whether there is metastatic disease to other organs. Laboratory test will exhibit elevated WBC and AST. A complete blood count (CBC) is a common laboratory test used to measure blood counts (or the number of blood cells circulating in the bloodstream). A CBC measures the level of red blood cells (which carry oxygen throughout the body), white blood cells (which fight infection), and platelets (which help with blood clotting) in a blood sample. A CBC also measures hemoglobin (a protein in red blood cells that carries oxygen) and hematocrit (the ratio of red blood cells to

These tests also help nurses and physicians to see the fluctuations that take place from time of admission. The patient came in with low RBC’s which may be caused by her chronic kidney failure. Erythropoietin is excreted by the kidneys to gather more red blood cells. When the kidneys are not functioning, this may inhibit the excretion of erythropoietin, causing a low red blood cell count. She also came in with low hemoglobin levels which indicates anemia which also goes hand in hand with her low red blood cell count because hemoglobin is a protein located within red blood cells that carries oxygen from the lungs to the body and tissues. E.M. lastly appeared to have low hematocrit levels this again, is associated with the patient's anemia this is the proportion of blood that contains red blood cells, and in this patient's case is very

According to the National Heart, Lung, and Blood Institute report, tests to measure iron levels are the serum ferritin, serum iron, and transferrin level. Tests will look at mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC). Complete blood count (CBC) looks at your hemoglobin and hematocrit levels. Red blood cells, white blood cells, and platelets are accessed. Abnormal results may indicate a blood disorder, infection or another condition. (2014)

The absorption of light by normal bilirubin (4Z,15Z-bilirubin) results in the creation of 2 isomeric forms of bilirubin: structural isomer (Z-lumirubin) and configurational isomer (4Z,15 E -bilirubin). Both these structural and configurational isomers of bilirubin have substantially different chemical and light absorption properties than bilirubin, are less lipophilic than normal bilirubin and can be excreted into bile without undergoing glucuronidation in the liver. The absorption of light by bilirubin also results in the generation of excited-state bilirubin molecules that react with oxygen to produce colorless oxidation, or photooxidation products. The rate of formation of bilirubin photoproducts is highly dependent on the intensity and wavelengths of the light used (13). The most efficient wavelength for the isomerization of bilirubin is approximately 450 nm, whether applied to the fluid samples for testing or the treatment of jaundice. Wavelengths that fall within the range of 400 nm-500 nm, and more specifically 445 nm-475 nm are known to effect isomerization (14). The blue lights are chosen for light emission wavelengths of approximately 450 to 530 nm, which is the optimal range of light absorption for bilirubin. In contrast, the optimal range of light absorption for

When the above mechanisms are overwhelmed by the increasing magnitude of the anemia, or when the demands of physical activity or intercurrent illness overwhelm them, a clinical disease state becomes apparent to the physician and to the patient. The severity of clinical symptoms bears less relationship to the severity of the anemia than to the length of time over which the condition develops. An acute hemorrhagic condition may produce symptoms with loss of as little as 20% of the total blood volume (or 20% of the total red cell mass). Conversely, anemias developing over periods long enough to allow compensatory mechanisms to operate will allow much greater loss of rbc mass before producing symptoms. It is not terribly uncommon to see a patient with a hemoglobin of 4

Discussion 1. The first part of this experiment focused on red blood cell lysis and its absorbance values, as well as its overall histology. In table 1, different solutions are used to test for the occurrence of red blood cell lysis and furthermore, their absorbance values. Although the values for table 1 were very scattered and varied greatly, it can be concluded that solutions of 5% and 2% NaCl had higher absorbance values at 640 nm, while the rest of the solutions read higher in the spectrometer at a reading of 540 nm. It appears as though the stronger the percentage of NaCl, the greater the absorbance.

Hemoglobin is present in red blood cells and carries oxygen from the lungs to tissues and returns carbon dioxide from tissues back to the lungs. Met Hemoglobin is a form of the oxygen-carrying part of Hemoglobin of which a small amount is present in human blood and produced automatically. However, if produced in large amounts it can cause coma and even death. Increased levels of Methaemoglobin can be caused by the ingestion of chemicals such as Cyanide and can be detected in blood stains at a scene of a crime as enhanced levels of Met Hemoglobin changes blood upon leaving the body from red to a dark brown in

The hemoglobin is determined using a non-cyanide analytical method from a dilution of whole blood.

Anemia is a common comorbidity in HF is associated with increased disease severity and also contributes to a worse outcome. The mechanism through which anemia contributes to negative outcome in chronic HF patients is multifactorial and complex. Important factors include, bone marrow resistance to erythropoietin, renal failure, chronic inflammation, medication use and hematinic deficiencies, in particular iron deficiency (ID). Generally, the presence of ID is only considered clinically relevant in the presence of anemia. However, a decreased hemoglobin levels can be viewed as the end result of a process beginning with gradual depletion of iron stores. Even if patients are not anemic, ID already may be common in chronic HF, with or without anemia, is associated with decreased aerobic performance and exercise intolerance, recently also shown in chronic HF.

After knowing the clearly knowing the differences between sickle cell anemia and normal hemoglobin Pauling and Itano still didn’t how or where the change occurred. The paper proposed that there was a difference in numbers of ionization groups between both hemoglobins. Itano specifically proposed there was a number variance in the globin or heme. He proposed along with Pauling that it is probable that normal and sickle cell anemia hemoglobin may have different globin

Iron is critical for hemoglobin production. Iron status test reflect the level of iron stored in tissue or the adequacy of iron for erythropoiesis.
