Blood

Blood is a bodily fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. In many species, it also carries hormones and disease-fighting substances. In this category, you will find questions about the blood in your body, including blood types, blood diseases, and the function of blood.

What does absolute eosinophils means?

User Avatar

Asked by Wiki User

Absolute eosinophils refers to the actual number of eosinophils present in a sample of blood, typically measured as part of a complete blood count (CBC) test. Eosinophils are a type of white blood cell that plays a role in the body's immune response, particularly in fighting off parasitic infections and allergic reactions. An increase in absolute eosinophil count may indicate various conditions, including allergies, asthma, parasitic infections, autoimmune diseases, and certain types of cancers. Conversely, a decrease in absolute eosinophil count may be associated with certain types of infections or bone marrow disorders.

If you're concerned about your Absolute Eosinophil counts or any other aspect of your health, it's essential to consult a qualified healthcare professional. Medicas offers Absolute Eosinophil count tests as part of comprehensive diagnostic services.

What test measurs percentage by volume of packed red blood cells in a whole blood sample?

User Avatar

Asked by Wiki User

In addition to hematocrit, another key blood parameter often measured is hemoglobin concentration, which represents the amount of oxygen-carrying protein within the red blood cells. Hemoglobin and hematocrit are closely related and provide complementary information about the blood's oxygen-carrying capacity and overall health status.

Hematocrit values can vary depending on factors such as age, sex, altitude, and certain medical conditions. For instance, low hematocrit levels may indicate anemia, blood loss, or nutritional deficiencies, while high levels could suggest dehydration, polycythemia vera, or other underlying health issues.

Interpreting hematocrit results typically involves consideration of the patient's medical history, symptoms, and other laboratory findings to guide diagnosis and treatment decisions. In clinical practice, Medicas are providing packed cell volume (pcv)test, for measuring the routinely performed as part of a complete blood count (CBC) test to assess various aspects of blood composition and function.

What are regulatory functions of blood?

User Avatar

Asked by Wiki User

Blood plays crucial regulatory functions in the body, helping maintain homeostasis and supporting various physiological processes. Some of the key regulatory functions of blood include:

Transportation of Oxygen and Nutrients: Blood carries oxygen from the lungs to cells and tissues and transports nutrients, such as glucose and amino acids, from the digestive system to cells for energy and growth.

Removal of Waste Products: Blood transports waste products, such as carbon dioxide and urea, from cells and tissues to the lungs and kidneys for elimination from the body.

pH Regulation: Blood helps regulate the body's pH by carrying buffers that minimize changes in acidity or alkalinity. This is crucial for maintaining the proper pH environment for enzymatic and metabolic processes.

Temperature Regulation: Blood helps regulate body temperature by absorbing and distributing heat. It carries heat away from active areas, such as muscles, to cooler areas and plays a role in temperature homeostasis.

Fluid Balance: Blood helps maintain fluid balance in the body by distributing water between cells and the extracellular fluid, ensuring proper hydration and preventing excessive fluid loss or accumulation.

Immune Response: Blood contains white blood cells (leukocytes) and antibodies that contribute to the body's immune response. They help defend against infections, pathogens, and foreign substances.

Clotting and Hemostasis: Platelets and clotting factors in the blood play a vital role in preventing excessive bleeding and promoting wound healing. The clotting process, known as hemostasis, helps control bleeding and maintain vascular integrity.

Hormone Transportation: Blood carries hormones from endocrine glands to target cells or organs, facilitating communication between different parts of the body and regulating various physiological processes.

Electrolyte Balance: Blood helps maintain the balance of electrolytes, including sodium, potassium, calcium, and others, which are essential for proper cellular function, nerve transmission, and muscle contraction.

These regulatory functions highlight the dynamic and essential role that blood plays in supporting overall health and ensuring the proper functioning of various systems within the body.

In any given 3mm of blood what is the approximate ratio of the number of red blood cells erythocites to white blood cells leukocytes?

User Avatar

Asked by Wiki User

There are about a thousand times as many red blood cells as white cells.

Consider that the red blood cells (or erythrocytes) in a mm3 (or microliter) of blood number about five million in an average man (a few less in a woman). The white blood cells (or leukocytes) number only 5-6 thousand per mm3 so the ratio is about a thousand fold.

What is level of liver enzyme in term pregnancy accepted as normal level?

User Avatar

Asked by Wiki User

Liver enzyme levels can vary among individuals, and what is considered a normal range can depend on the specific laboratory that analyzes the blood tests. Generally, during pregnancy, some changes in liver enzyme levels are expected, and it's essential to interpret these results in the context of pregnancy-related adaptations.

The two primary liver enzymes that are often measured in blood tests are alanine aminotransferase (ALT) and aspartate aminotransferase (AST). These enzymes are released into the bloodstream when there is liver cell damage or inflammation.

During pregnancy, it is common for liver enzyme levels to be slightly elevated, especially in the second and third trimesters. Mild elevations are generally considered normal and are often attributed to the physiological changes that occur during pregnancy.

As a reference, normal ranges for liver enzymes in non-pregnant adults are typically:

ALT (Alanine Aminotransferase): 7 to 56 units per liter (U/L)

AST (Aspartate Aminotransferase): 8 to 48 U/L

It's important to note that reference ranges may vary between laboratories, and healthcare providers usually take these variations into account when interpreting results.

During pregnancy, a mild elevation in liver enzyme levels may be considered normal, but significant or persistent elevations may warrant further investigation. Elevated liver enzymes can be associated with conditions such as preeclampsia, intrahepatic cholestasis of pregnancy (ICP), or other liver-related issues.

If you are pregnant and have concerns about your liver enzyme levels, it's crucial to discuss the results with your healthcare provider. They will be able to interpret the values in the context of your overall health and pregnancy and may order additional tests or investigations if necessary. Regular prenatal care, including routine blood tests, helps monitor and ensure the well-being of both the mother and the developing fetus.

What is toxicology?

User Avatar

Asked by Wiki User

Toxicology is the study of poisons or hazardous substances and how they influence living organisms such as humans. It assists us in understanding the adverse effects of chemicals, medications, and other substances on the body, as well as how to avoid or treat poisoning. Toxicologists study how much of a material is required to produce harm, how it enters and moves through the body, and how the body responds to it. This knowledge is critical for assuring product, pharmaceutical, and environmental safety.

You can know more about toxicology and learn toxicology concepts through an online course - Forensic Medicine and Toxicology for UnderGrads.

The course is a perfect course for students looking to know about toxicology, as it provides in-depth explanations of topics and provides them with a tremendous amount of knowledge, which helps them in laying a strong foundation for their future.

How does sickle cell hemoglobin differ from normal hemoglobin?

User Avatar

Asked by Wiki User

Sickle cell hemoglobin differs from normal hemoglobin primarily due to a single amino acid substitution in the hemoglobin protein chain. In sickle cell disease, a person inherits two copies of an abnormal hemoglobin gene, usually referred to as HbS.

In normal hemoglobin (HbA), the amino acid glutamic acid is present at a specific position in the beta chain of the hemoglobin protein. However, in sickle cell hemoglobin (HbS), this glutamic acid is replaced by valine due to a genetic mutation. This change causes the hemoglobin molecules to stick together under certain conditions, forming long, rigid structures that distort red blood cells into a sickle or crescent shape.

Is hemoglobin organic or inorganic?

Asked by Wiki User

Yes, foil is made from a single huge block of aluminum. The block is rolled between massive industrial rollers over and over again. The aluminum gets thinner and longer with each pass through the rollers until it is as thin as foil. For the very last 'roll' the foil is too thin to go through alone, so they put two sheets together, it is because of this 'double' final roll that the foil gets a shiny side and a dull side.

There are a number of posts on the web of short video clips a couple of minutes long showing the making of aluminum foil. YouTube and other sites have them. Use the link below to related questions.
Aluminium foil is made of the metal - aluminium., with a thickness of less than 0.2mm

Why blood for testing is drawn from left ring finger?

User Avatar

Asked by Wiki User

I have had multiple blood draws done every year since the middle 1990s and the blood has always been taken from veins in my forearm (sometimes left, sometimes right) near the elbow, never the hands or fingers.

Diabetic blood sugar tests are often taken from the fingertips, but there is a tendency for many new test devices to get away from this and use the arm because the fingertips are more pain sensitive than the arms.

I cannot think of any reason a blood test would have to be taken only from a single finger.

What are the major functions fo plasma proteins in the blood?

User Avatar

Asked by Wiki User

There are numerous kinds of proteins in the blood, thus proteins have many important functions. The major ones are:

  • molecule transportation (Ex.: Lipoproteins make it possible for cholesterol to move freely in the aqueous environment of the organism);
  • immunity;
  • coagulation of blood (clots are made thanks to a reaction chain occurring between many kinds of proteins, the ''coagulation factors'');
  • the maintain of oncotic pressure in blood vessels(oncotic pressure is a part of the osmotic pressure between the plasmatic and the lympatic environments).

Other functions exist, though.

Plasma proteins perform various functions. Plasma contains hundreds of proteins each having their specific function. A major protein is Albumin, which is responsible for transport of fatty acids, lipids, drugs etc in the body, it also maintains the osmotic balance with body. Albumin is followed by Immunoglobulins, which are responsible for the immune response. Fibrinogen is responsible for the blood clotting at the time of injury. There is a long list of proteins and an even longer list of their functions.

Is having small spots of brown blood menstruation?

User Avatar

Asked by Wiki User

Brown just means it is old blood, rather than fresh. A spotty, brown discharge during your period is a sign of an irregular period, and isn't necessarily abnormal. Many women experience it at least once in their lives, or even on a recurring basis. You can talk to your doc if you think there might be something wrong, or if you have abnormal pain.

How early can you have an HCG blood test done?

User Avatar

Asked by Wiki User

For best results:

* Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest * Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results * Take the test no more than 1-2 days before expected period. Although some test say that you can see results up to 5 days before your missed period the percentage of accuracy is very low. * urinate for as long as possible on the foam like strip * wait for the results

No. For a child to have AB, one parent must have either A or AB and the other must have B or AB. O is a recessive type to both, so neither parent has any of those bloodtypes; their child will be O.

Why is there bleeding after urinating?

User Avatar

Asked by Wiki User

You could have a kidney or bladder infection. The only way to get rid of it is to see a doctor. Another possibility is a kidney or bladder stone. The stone forms in the kidney and causes bleeding as it travels down the ureter to the bladder. Once the stone is in the bladder it may not cause bleeding again until it begins to travel down the urethra when one urinates. Both infections and stones can be painful. Infections can be very dangerous if the kidney becomes involved. Similarly a stone trapped in the kidney could disastrously affect the production of urine. Medical attention is important if there is blood in the urine.
