Notes

Full blood counts are performed on automated equipment and provide haemoglobin concentration, red cell indices, white cell count (with a differential count) and platelet count.
The presence of abnormal white cell and red cell morphology is flagged by the analysers.
Blood films may be inspected to confirm and interpret abnormalities identified by the cell counter, or to look for certain specific haematological abnormalities.
Grossly abnormal FBC results and abnormal blood films will be phoned through to the requestor.
There is no need to request a blood film to obtain a differential white count. It is, however, important that clinical details are provided to allow the laboratory to decide whether a blood film, in addition to the automated analysis, is required.
Under some circumstances a differential is not routinely performed, e.g. pre-op, post-op, antenatal and postnatal requests.

What is hematology? Hematology is the study of blood and blood disorders. Hematologists and hematopathologists are highly trained healthcare providers who specialize in diseases of the blood and blood components. These include blood and bone marrow cells.
 
What is the difference between a hematologist and a hematopathologist?


A hematologist is usually a board-certified internist, or pediatrician who has completed additional years of training in hematology. The hematologist generally focuses on direct patient care and diagnosing and managing hematologic disease, especially cancers.


A hematopathologist is usually board-certified in both anatomical and clinical pathology and has additional years of training in hematopathology. Hematopathology is not only the study of disease of the blood and bone marrow. It is also the study of the organs and tissues that use blood cells to perform their physiologic functions. These include the lymph nodes, the spleen, thymus, and other lymphoid tissue. The hematopathologist focuses on the diagnosis of conditions of the hematopoietic and lymphocyte-rich tissues. This is usually done by direct exam of tissue and blood in the lab. 

 Hemoglobin is an iron-rich protein in red blood cells (RBCs).   The normal hemoglobin range for men is 13.5 to 17.5 gm/dL and 12 to 15.5 gm/dL for women. It is of utmost importance to maintain hemoglobin concentration.

What functions does hemoglobin perform in our bodies? 
Hemoglobin is vital for carrying oxygen from the lungs to tissues and organs. It also transports carbon dioxide from the tissues back to the lungs.
What causes low hemoglobin?

Some common causes of low hemoglobin are:

Substantial blood loss
Deficiency in iron, vitamin B, and folate
Kidney disease
Hypothyroidism
Thalassemia
Lung diseases
Excessive smoking

Any type of blood loss can cause anemia, including blood loss from surgery, heavy menstrual periods, and bleeding in the gastrointestinal tract. 
Symptoms of low hemoglobin
You can detect extremely low hemoglobin levels in your system in a few ways. They include

A fast or irregular heartbeat
Fatigue
Frequent or unexplained bruising
Shortness of breath
Liver and kidney disease
Pale skin and gums
Muscle weakness
Reoccurring headaches
Dizziness
Poor appetite
Anemia in severe cases

Elevated hemoglobin levels are associated with dehydration, heart failure, and chronic lung disease. In some conditions, the bone marrow may not produce enough RBCs, leading to cancers like leukemia, lymphoma, or tumors that spread from other parts of the body into the bone marrow.
What are the foods that can improve your hemoglobin levels?

It is essential to boost your food intake to raise your hemoglobin levels. Here are some foods to increase hemoglobin levels:

Iron-rich foods: Consume iron-rich foods like fish, meat, eggs, soy products, broccoli, green leafy vegetables that include spinach, fenugreek leaves, cauliflower, green peas, cabbage, green beans, nuts and seeds, and peanut butter, to increase your hemoglobin levels.
Vitamin A: It is pertinent to consume vitamin A foods to increase hemoglobin as they absorb more iron. Vitamin A and beta-carotene can help you there. Vitamin A is found in animal food sources, such as fish and liver. Beta-carotene is found in red, yellow, and orange fruits and vegetables.
Folate: Folate is a type of Vitamin B that plays an essential part in hemoglobin production. A shortage of folate can prevent the red blood cells from maturing, leading to anemia. Some good sources of folate include beef, rice, black-eyed peas, kidney beans, lettuce, and peanuts.
Foods rich in vitamin C: A combination of iron and vitamin C can prove to be beneficial. The latter is used for better absorption of iron. Foods rich in vitamin C include oranges, lemon, strawberries, papaya, bell peppers, broccoli, and tomatoes.
Fruits: It is also perfect to have fruits like beetroot, apple, watermelon, papaya, oranges, litchis, kiwis, strawberries, grapefruit, banana, and peach, which can boost hemoglobin levels. Plus, dry fruits, like dates, can increase the number of erythrocytes, thereby increasing hemoglobin levels. They contain iron, vitamin C, vitamin B complex, and folic acid, which helps in the formation of red blood cells. Raisins are also a rich source of iron and copper necessary to form red blood cells.

Avoid iron blockers: Foods that block your body’s ability to absorb iron, such as coffee, tea, alcohol, and aerated drinks, should be avoided.
Tips to increase your hemoglobin levels
Here are some tips to keep in mind to increase your hemoglobin levels:
Switch to brown rice: As a superfood, brown rice can help prevent various diseases related to cholesterol and the gastrointestinal system. It is rich in iron, containing 0.52 milligrams of iron for every 100 grams.
Enjoy dark chocolate: With over 80% of cocoa, dark chocolate naturally improves hemoglobin levels. Plus, it is loaded with minerals, nutrients and antioxidants.
Drink nettle tea: The spice nettle has also proven to be a good source of iron and vitamin B and C. They can also play a part in increasing hemoglobin levels.
 Exercise: Take up moderate to high-intensity exercise to help your body produce more hemoglobin to meet the oxygen demands of your body.

What is SDLC?
SDLC is a process followed for a software project, within a software organization. It consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.
The following figure is a graphical representation of the various stages of a typical SDLC.

A typical Software Development Life Cycle consists of the following stages −
Stage 1: Planning and Requirement Analysis
Requirement analysis is the most important and fundamental stage in SDLC. It is performed by the senior members of the team with inputs from the customer, the sales department, market surveys and domain experts in the industry. This information is then used to plan the basic project approach and to conduct product feasibility study in the economical, operational and technical areas.
Planning for the quality assurance requirements and identification of the risks associated with the project is also done in the planning stage. The outcome of the technical feasibility study is to define the various technical approaches that can be followed to implement the project successfully with minimum risks.
Stage 2: Defining Requirements
Once the requirement analysis is done the next step is to clearly define and document the product requirements and get them approved from the customer or the market analysts. This is done through an SRS (Software Requirement Specification) document which consists of all the product requirements to be designed and developed during the project life cycle.
Stage 3: Designing the Product Architecture
SRS is the reference for product architects to come out with the best architecture for the product to be developed. Based on the requirements specified in SRS, usually more than one design approach for the product architecture is proposed and documented in a DDS - Design Document Specification.
This DDS is reviewed by all the important stakeholders and based on various parameters as risk assessment, product robustness, design modularity, budget and time constraints, the best design approach is selected for the product.
A design approach clearly defines all the architectural modules of the product along with its communication and data flow representation with the external and third party modules (if any). The internal design of all the modules of the proposed architecture should be clearly defined with the minutest of the details in DDS.
Stage 4: Building or Developing the Product
In this stage of SDLC the actual development starts and the product is built. The programming code is generated as per DDS during this stage. If the design is performed in a detailed and organized manner, code generation can be accomplished without much hassle.
Developers must follow the coding guidelines defined by their organization and programming tools like compilers, interpreters, debuggers, etc. are used to generate the code. Different high level programming languages such as C, C++, Pascal, Java and PHP are used for coding. The programming language is chosen with respect to the type of software being developed.
Stage 5: Testing the Product
This stage is usually a subset of all the stages as in the modern SDLC models, the testing activities are mostly involved in all the stages of SDLC. However, this stage refers to the testing only stage of the product where product defects are reported, tracked, fixed and retested, until the product reaches the quality standards defined in the SRS.
Stage 6: Deployment in the Market and Maintenance
Once the product is tested and ready to be deployed it is released formally in the appropriate market. Sometimes product deployment happens in stages as per the business strategy of that organization. The product may first be released in a limited segment and tested in the real business environment (UAT- User acceptance testing).
Then based on the feedback, the product may be released as it is or with suggested enhancements in the targeting market segment. After the product is released in the market, its maintenance is done for the existing customer base.Video link:Embedded video link:Link: https://projects.invisionapp.com/d/main#/console/20294675/458743820/preview 

graphical user interface:
The graphical user interface (GUI  is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicators such as primary notation, instead of text-based user interfaces, typed command labels, or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.
The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones, and smaller household, office, and industrial controls. The term GUI tends not to be applied to other lower-display resolution types of interfaces, such as video games ), or not including flat screens, like volumetric displays.
User interface and interaction design:
Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human-computer interaction. Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline named usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks.
The visible graphical interface features of an application are sometimes referred to as chrome or GUI (pronounced gooey) Typically, users interact with information by manipulating visual widgets that allow for interactions appropriate to the kind of data they hold. The widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of users.
