Pathology Postgraduate Primer: Navigating Your First Year

Urine analyzers are instruments used to analyze the physical, chemical, and microscopic properties of urine. Here are some examples of urine analyzers: Automated Urine Analyzers: These are the most common type of urine analyzer used in clinical laboratories. They use various methods such as photometry, colorimetry, and ion-selective electrodes to measure urine parameters such as pH, specific gravity, protein, glucose, ketones, and leukocytes. Urine Sediment Analyzers: These analyzers are specifically designed to analyze the microscopic components of urine, such as red blood cells, white blood cells, and epithelial cells. They use advanced optics and image processing techniques to generate high-resolution images of the urine sediment and provide quantitative data on cell counts and morphology. Urine Dipstick Analyzers: These are simple, handheld devices that are used to rapidly test for several urine parameters such as pH, protein, glucose, and leukocytes. They work by using chemical re...

Sysmex XN-Series: A popular line of hematology analyzers that use flow cytometry and fluorescence technology to analyze white blood cells, red blood cells, and platelets. Beckman Coulter LH 750: A hematology analyzer that utilizes a combination of impedance and optical methods to measure cell counts and various parameters such as cell size, hemoglobin concentration, and cell morphology. Abbott CELL-DYN: A hematology analyzer that uses impedance, optical and fluorescence methods to measure various parameters of blood cells and plasma, including cell count, size, and morphology. Siemens Advia: A hematology analyzer that uses flow cytometry and laser light scattering technology to measure white blood cell differentials, red blood cell indices, and platelet counts. Horiba ABX Pentra: A hematology analyzer that uses impedance and optical methods to measure various parameters of blood cells, including cell count, size, and morphology. Mindray BC Series: A line of hematology analyzers that us...

Platelet Large Cell Ratio (P-LCR) is a measure of the percentage of large platelets in the blood, and it is commonly used as a marker of platelet function. The P-LCR is obtained by measuring the size and shape of platelets in a blood sample and expressing the percentage of larger-than-normal platelets as a ratio of the total number of platelets in the sample. In this blog post, we will discuss what P-LCR is, how it is measured, and what it can tell us about platelet function. Platelets are small, irregularly-shaped cells that are formed in the bone marrow and are essential for blood clotting. When blood vessels are damaged, platelets stick together to form a plug that stops bleeding. The size and shape of platelets can vary depending on their age and their function. Large platelets are often associated with increased platelet activation and may reflect an increased demand for platelet function. P-LCR is determined using a blood sample that is analyzed by an automated blood analyzer. Th...

The erythroid series of cells, also known as erythropoiesis, is the process of producing red blood cells in the bone marrow. The erythroid series of cells includes the following stages: Proerythroblast: This is the earliest stage of red blood cell development, and it is characterized by the presence of a large nucleus and a small amount of cytoplasm. Basophilic erythroblast: At this stage, the red blood cell precursor begins to synthesize hemoglobin, which gives it a blue color when stained. Polychromatophilic erythroblast: At this stage, the red blood cell precursor has increased its hemoglobin synthesis and begins to lose its blue color, becoming more pink or purple. Orthochromatic erythroblast: This stage is characterized by the complete synthesis of hemoglobin and the expulsion of the nucleus. The cell is now a reticulocyte. Reticulocyte: This is the final stage of red blood cell development before it becomes a mature erythrocyte (red blood cell). Reticulocytes still contain some r...

Cells in your Blood! The human body is an incredible and complex system made up of different types of cells working together to keep you healthy. In the bloodstream, there are several types of cells, including red blood cells, white blood cells, and platelets. These cells are essential to your health, and their levels in your peripheral blood can provide crucial information about your overall well-being. Red Blood Cells (RBCs): Red blood cells, also known as erythrocytes, are the most abundant cells in the bloodstream. They are responsible for carrying oxygen from the lungs to other parts of the body and bringing back carbon dioxide to be removed. RBCs are disk-shaped and contain hemoglobin, a protein that binds to oxygen and gives them their characteristic red color. The normal range of RBCs in peripheral blood is 4.5 to 5.5 million cells per microliter for men and 4.0 to 5.0 million cells per microliter for women. White Blood Cells (WBCs): White blood cells, also called leukocytes, a...

Basic Concepts in Hematology: A Primer for Pathology Residents Hematology is a critical part of pathology, focusing on the study of blood and blood-forming tissues. As a first-year pathology resident, it is essential to have a good understanding of basic hematology concepts to provide accurate diagnoses and understand the implications of various blood disorders. In this blog post, we will cover some of the fundamental concepts in hematology that every first-year pathology resident should know. Components of Blood Blood is made up of four main components: red blood cells (RBCs), white blood cells (WBCs), platelets, and plasma. RBCs are responsible for carrying oxygen to tissues, WBCs are essential for fighting infections, and platelets are critical for blood clotting. Plasma is the fluid component of blood that carries nutrients, hormones, and waste products throughout the body. Complete Blood Count (CBC) One of the most common tests ordered in hematology is a complete blood count (CBC)...

Introduction to Pathology: What Every First Year Resident Should Know  As a first year pathology resident, you are entering a new world of medicine. Pathology is a broad field that encompasses a variety of disciplines including hematology, cytology, histopathology, microbiology, and immunology. It can be overwhelming to navigate all of these areas, especially if you are new to the field. Here are some key things you should know as you begin your residency in pathology: Understanding the basics: Before diving into the specifics of different areas of pathology, it is important to have a solid understanding of the basics. This includes knowledge of cell and tissue structure, the pathology of different organ systems, and the biochemical pathways that underlie many disease processes. Hematology: Hematology is the study of blood and blood-forming tissues. As a pathologist, you will need to be able to interpret blood cell counts, understand the different types of anemia, and recognize the...
