Blood Cell Lab

In the Core Lab, I was assigned to hematologist named Melissa. She was very experienced in her work since she knew how to operate machines that help her detect any abnormalities in the blood samples. Regularly, the hematologists and other lab workers would work independently, and I like the method of independent labor because there won’t be any obstacles while testing in the lab. I also liked observing the blood samples through microscope and see whether the blood have any kinds of disease or irregularity. The hematology was very interesting and enjoyable; I was able to experience and learn that hematology is another way to test and figure out life threatening unusualness in the body.

The goal of this experiment is to determine the blood types of the samples given and to learn what interactions occurred to each blood type. Determining an individual’s blood type and how it reacts with Anti A, Anti-B, and Anti Rh serums played a crucial part in this experiment. The researcher concluded that agglutination (clumping) occurred in some of the blood samples. For example, Mr. Smith’s blood reacted with Anti-A and Anti-Rh serums (antibodies) allowing the researcher to determine the blood type is A. Mr. Jones’s blood reacted with Anti-B serum but it did not react to Anti-A or Anti Rh allowing the researcher to believe that the blood type is B. Mr. Green’s blood reacted with all serums and caused a reaction to occur resulting the blood type to be AB positive. Mr. Green’s blood also had a positive marker for Rh factor. However, Ms. Brown’s blood had no reaction at all and the researcher determined if no reaction occurred then the sample had no antigens but proved to have some antibodies, resulting in blood type to be O. The purpose of this experiment is to determine whose blood has type A, B, AB, or O.

Complete Blood Cell Count (CBC): White blood cell count (WBC), Red blood cell count (RBC), Hematocrit (Hct), Hemoglobin (Hgb),Platelets (Plt)

To identify red blood cells, basophils, eosinophils, monocytes, lymphocytes, neutrophils, sickle cell anemia and leukemia.

In this paper I will answer some questions about blood and related issues. Some of the questions I will answer are: what is the significance of a lower than normal haematocrit? what is erythropoiesis?why would the level of leukocytes be higher in an individual who has been infected with a parasitic disease. In regions where malaria is endemic, some people build up immune resistance to the malaria pathogen. Which WBCs are responsible for the immune response against pathogens? How do they function?

Experiment 1 In our first experiment, our question was which cell fraction would have the greatest amount of chloroplast present at an absorbance reading of 600 nm? To answer this question, we used centrifugation to separate out Pellet 1, Pellet 2, and Supernatant 2, and then we tested each of them at 600 nm three times to determine which one contained the most chloroplast. Based on our results for wet lab 1 we hypothesized that Pellet 2 would contain the most chloroplast. We predicted this because in wet lab 1, we learned that a homogenized solution contains all organelles, Pellet 1 contains large amyloplasts, and Pellet 2 contains chloroplasts and small amyloplasts (McAllister 83).

Exercise 11: Blood Analysis: Activity 1: Hematocrit Determination Lab Report Pre-lab Quiz Results You scored 75% by answering 3 out of 4 questions correctly. 1. Hematocrit Your answer : a. refers to the percentage of white blood cells (WBCs) in a sample of whole blood. Correct answer: b. of 40 means that 40% of the volume of blood consists of RBCs. 2. A buffy coat layer You correctly answered: d. is all of the above. 3. The diagnosis of anemia indicates You correctly answered: a. a lower-than-normal hematocrit. 4. Polycythemia refers to You correctly answered: c. a significant increase in RBCs.

When foreign antigens enter the body, chemical signals are dispatched to different parts of the immune system and send it into action.  B lymphocytes produce the antigen specific antibodies.  The antibodies will then attach to the antigen/virus and T lymphocytes will attack the antigen that the antibody has bound itself to.  Once the antigen has been eliminated phagocytes, which are cells that absorb bacteria and other small particles/substances, will come through and absorb the remains of the antigen/infection. In a forensic setting antibodies can also be used to identify an unknown blood/protein. The purpose of this experiment is to use the process of immunoprecipitation to identify an unknown host protein.

Many pink spheres and rod shapes (maybe Staphylococci and Streptobacillus), a few clusters with small dots (maybe ribosomes, rings of spherical chains, star shaped 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

In 1984, the Coen brothers made their debut with Blood Simple, a neo-noir film that would not be their last. While the Coens are influenced by film noirs, they, like filmmakers before them, draw inspiration from the works of Dashiell Hammett and James M. Cain as well. Even though the Coens utilize concepts and conventions from film noir and hard-boiled fiction, they do not shy away from reinventing these formulas in Blood Simple. Before exploring how the Coens reinvent the formulas from past works, it is important to understand what preceded and influenced neo-noir: film noir.

The following Red Cell Analysis will seek to provide the best suitable data collection programs to be utilized in gathering intelligence on the Islamic State of Iraq and Syria (ISIS), an explanation on which members of the Intelligence Community (IC) would be the best collectors of intelligence on ISIS and lastly, what intelligence analysis strategies would be the most effective on ISIS. Additionally, the origins, funding, and capabilities of ISIS will be provided for reference.

The purpose of this lab is to correctly determine the blood type of four unknown synthetic blood samples through the use of three antibody serums; anti-A, anti-B and anti-Rh. By successfully determining the blood type of an individual, information such as the individual 's blood antigens and antibodies will be known and can help determine which blood types that individual can accept or donate.

Methodology and Principal Findings: First of all, we made every materials that we need ready. First step was wiped a finger with alcohol, stacked it with lancet. Then, we collected amount of blood in a capillary tube. We left it about one and half hour to collect a plasma with white blood cells. Second step prepared in bottom Petri dish with tap water and filter paper, placed the bent rod

Can be performed on either a blood smear sample or a hemocytometer using a standard microscope system. for a hemocytometer, the gridded area is scanned for the counting purpose, to identify the numbers of different white cells, a blood film is made, and a large number of white blood cells (at least 100) are counted. This gives the percentage of cells that are of each type. By multiplying the percentage with the total number of white blood cells, the absolute number of each type of white cell can be obtained. Although the manual method is more laborious and time consuming, it is useful in cases where automated analyzers cannot reliably count abnormal cells,
