  Difference between Plasma and Serum Serum and plasma are obtained from the liquid portion of the blood that is obtained when the cells are removed. However, there is striking difference between plasma and serum. Serum is the liquid that remains after the clotting of blood. Whereas, plasma is the liquid that remains when anticoagulant is added to prevent clotting. Following are the important difference between plasma and serum: Plasma Serum A transparent, straw-coloured, liquid portion of the blood. An undiluted fluid, the extracellular portion of blood. It is composed of serum and clotting factor. It is the part of the blood which lacks clotting factor. It is acquired after centrifuging blood with the anticoagulant. It is acquired after centrifuging of coagulated blood. Anticoagulant is required to obtain plasma from the blood sample. Anticoagulant is not required to separate the serum from the blood sample. Consists of 55% of the total volume of blood. Less volume in comparison ...

  What is alkaline phosphatase? ALP is an enzyme found in your bloodstream. It helps break down proteins in the body and exists in different forms, depending on where it originates. Your liver is one of the main sources of ALP, but some is also made in your bones, intestines, pancreas, and kidneys. In pregnant women, ALP is made in the placenta. What is an alkaline phosphatase level test? An alkaline phosphatase level test (ALP test) measures the amount of alkaline phosphatase enzyme in your bloodstream. The test requires a simple blood draw and is often a routine part of other blood tests. Abnormal levels of ALP in your blood most often indicate a problem with your liver, gallbladder, or bones. However, they may also indicate malnutrition, kidney cancer tumors, intestinal issues, a pancreas problem, or a serious infection. The normal range of ALP varies from person to person and depends on your age, blood type, gender, and whether ...

  What is a G6PD test? A G6PD test measures the levels of glucose-6-phosphate dehydrogenase (G6PD), an enzyme in your blood. An enzyme is a type of protein that’s important for cell function. G6PD helps red blood cells (RBCs) function normally. It also protects them from potentially harmful byproducts that can accumulate when your body is fighting infection or as the result of certain medications. A lack of G6PD may make RBCs more vulnerable to breaking down in a process called hemolysis. A G6PD test is a simple test that requires a blood sample. It’s typically ordered to test for G6PD deficiencies. What are the symptoms of G6PD deficiency? Symptoms of G6PD deficiency can include: rapid heart rate shortness of breath urine that is dark or yellow-orange fever fatigue dizziness paleness jaundice, or yellowing of the skin and whites of the eyes

  What are epithelial cells? Epithelial cells are cells that come from surfaces of your body, such as your skin, blood vessels, urinary tract, or organs. They serve as a barrier between the inside and outside of your body, and protect it from viruses.

  What is ELISA? (Enzyme-linked Immunosorbent Assay) Enzyme-linked Immunosorbent Assay (shortened as ELISA) is used to identify peptides, proteins, antibodies and hormones . Also, called as enzyme immunoassay (EIA), ELISA finds use in the fields of biotechnology and medicine as a diagnostic tool. Mainly, antibodies and color changes are used to identify target substances. Also, ELISAs are useful in measuring antigen and antibody concentration. ELISA Principle ELISA works by coupling antibody or antigen to assay enzyme. The assay combines the specificity of antibody and sensitivity of assay enzymes to primarily detect antigens through assay antibody or antibodies through assay antigens. The sensitivity and precision of the assay is enhanced by coating the plate with high-affinity antibodies.

  What is hypoparathyroidism? Hypoparathyroidism is a rare condition that occurs when the parathyroid glands in the neck don’t produce enough parathyroid hormone (PTH). Everyone has four parathyroid glands located near or behind the thyroid gland. Each gland is the size of a grain of rice. The major function of PTH is to regulate the level of calcium in your body. It also controls the level of phosphorus and has a role in the production of the active form of vitamin D. All of these activities are required to maintain calcium balance. Having too little PTH causes low levels of calcium and high levels of phosphorus in the body. This condition may not cause any serious medical problems when it’s caught early, but it does require lifelong monitoring and treatment.

  The Difference Between DNA And RNA DNA stands for  deoxyribonucceic acid , while RNA is  ribonucleic acid . Although DNA and RNA both carry genetic information, there are quite a few differences between them.  Summary of Differences Between DNA and RNA 1.DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. 2.DNA is a double-stranded molecule, while RNA is a single-stranded molecule. 3.DNA is stable under alkaline conditions, while RNA is not stable. 4.DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins. 5.DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thy...

PARTS OF SYRINGE 1. The Parts of a Syringe Print this article A needle syringe is a device used for injecting, removing or infusing fluids. They are most commonly known in health care settings for injecting medications and for use in removing blood from the body. Syringes can differ in size and type, and they can be made of glass or plastic. The syringe chosen usually depends on its intended purpose. The syringe consists of a plunger, barrel, hub, needle and the needles protective cover. It is important that all parts of a syringe coming into contact with the body be kept free of contamination. Related Searches: 22 Gauge Syringe Retractable Plunger1. The Plunger o The plunger is located at the end of the syringe and can be made of clouded or colored glass or plastic. Its purpose is to fill or empty the barrel. The plunger is pulled back to fill the barrel and is pushed forward for emptying. The Barrel o The barrel is the part of the syringe that contains the fluid, whether it is a ...

  Composition Of Blood There are many cellular structures in the composition of blood.  When a sample of blood is spun in a centrifuge machine, they separate into the following constituents: Plasma, buffy coat and erythrocytes. Plasma The liquid state of blood can be contributed to plasma as it makes up  ~55% of blood. It is pale yellow in colour and when separated, it consists of salts, nutrients, water and enzymes. Blood plasma also contains important proteins and other components necessary for overall health. Hence, blood plasma transfusions are given to patients with liver failure and life-threatening injuries. Red Blood Cells (RBC) Red blood cells consist of Haemoglobin, a protein. They are produced by the bone marrow to primarily carry oxygen to the body and carbon dioxide away from it. White Blood Cells (WBC) White blood cells are responsible for fighting foreign pathogens (such as bacteria, viruses, fungi) that enter our body. They circulate throughout our body an...

  What is an ESR test? An erythrocyte sedimentation rate (ESR) test is sometimes called a sedimentation rate test or sed rate test. This blood test doesn’t diagnose one specific condition. Instead, it helps your healthcare provider determine whether you’re experiencing inflammation. Your doctor will look at ESR results along with other information or test results to help figure out a diagnosis. The tests ordered will depend on your symptoms. The ESR test can also be used to monitor inflammatory diseases.
