Lab Values: Everything You Need to Know about Laboratory Medicine and its Importance in the Diagnosis of Diseases
Lab First Edition
The second edition is available for purchase with more content and updates. To find it right away, type "Lab Values Second Edition" in the search field. Make sure the publisher is Medical Creations.Let’s be very clear about this, the best way to start studying a new topic is to learn the basic fundamentals first before you dive into the details. That way, you will not get overwhelmed because you will understand the bigger picture first. The problem with many medical books is that they are overly detailed and therefore bad in painting the bigger picture. Our Lab Values book solves this problem by making you learn the basic fundamentals first before you dive into the details with other, more detailed, medical books. This book serves two purposes; It’s a great introduction for those that want a simple overview, and it’s also great for students looking for a quick recap that covers the most important information. How do you best prepare for an exam? If you don't have the time, you just recap the fundamentals. To test your knowledge, we have included multiple choice questions after each chapter. The answers to these questions can be found at the very end.
Let’s face it, the skill of being able to interpret laboratory investigations and to understand the science behind it is extremely important in the field of medicine.It is said that approximately 60-70% of decision making in medicine is done based on the results of laboratory tests. Laboratory values essentially provide data in an objective form that relates to the patient’s health. They can aid in early diagnosis of diseases that have not yet had clinical manifestations, thereby leading to more effective management of such conditions. They can also aid in monitoring the progress of various diseases so that treatment can be modified accordingly. Insufficient understanding of laboratory tests in a clinical setting can lead to misinterpretation of results, which will jeopardize patient safety.With this book you ..Get an in-depth understanding of how the physiology of our bodies work..Be able to objectively measure your patient’s health..Use your new skills every single day at workGo to the top-right of the page and click "Add to Cart"

The National Council Licensure Examination NCLEX is a nationwide examination for the licensing of nurses in the United States, Canada, and Australia.
Large samples of blood are best obtained using evacuated blood tubes.
Venous samples: The area is prepared using an alcohol swab and allowed to air dry. The patient is asked to make a fist, and the skin is stretched taut over the vein. The needle is inserted into the vein at a 15 to 30 degree angle. The blood is collected into the syringe or vacutainer tube.
Capillary blood: This is a common method used for home testing, particularly in diabetic patients for monitoring blood glucose levels. The first drop is generally discarded as it contains tissue fluid.
OBTAINING A URINE SAMPLE: The patient must be instructed to collect a midstream sample.
OBTAINING A STOOL SAMPLE: Requisite amount of stool (around 10 ml) is scooped up using the spoon provided, and transferred to the specimen container. The container lid must be closed immediately.
______
• Hemoglobin is an iron containing protein that is found in red blood cells. It acts as a carrier for oxygen and carbon dioxide between the lungs and the various tissues of the body.
• Normal levels of hemoglobin are as follows:
Male: 12-17gms/100ml
Female: 11-15 gms/100ml
• Low hemoglobin is an indicator of anemia.
Normal white cell count: 4500 – 10500 cells per cu mm of blood.
The white blood cell count usually increases during infections. An extremely high rise in white blood cells can be an indication of malignant conditions such as leukemia. White blood cells are decreased during conditions of immunosuppression, due to various diseases or drugs.
Diabetes mellitus is one of the most common diseases in the developed world, caused due to ineffective secretion of the insulin hormone from the pancreas, which is responsible for metabolism of glucose.
When the patient eats, the blood glucose increases slightly, which stimulate the pancreas to release insulin. This in turn metabolizes the glucose and clears it from the blood within two hours. Therefore the postprandial blood sugar test is useful in assessing insulin function. Patients
There are two hormones secreted by the thyroid gland – T3 (Triiodothyronine) and T4 (Thyroxine).
Blood urea nitrogen:
• In the body, unutilized proteins and amino acids are generally broken down by the liver into urea and carbon dioxide.
• The urea is usually excreted by renal tubules. If the kidney fails to function, the levels of urea in the blood can increase. BUN is inversely proportional to the glomerular filtration rate.
• Normal values of BUN: 3 – 20 mg/dl
Uric acid:
• Uric acid is the final breakdown product of purine catabolism. It is produced by the liver and two thirds is eliminated by the kidney, with the rest being eliminated by the gastrointestinal tract.
• Normal values:
Males: 2.5 – 8 mg/dl
Females: 1.9 – 7.5 mg/dl
BUN: Creatinine ratio
< 10:1 is renal damage
Maple syrup urine disease has sweet smelling urine.
Stool pH:
• Normal stool pH is 7 to 7.5.
• A pH below 5.6 is characteristic of carbohydrate malabsorption.
