What is the difference between Wright stain and Giemsa stain?
The Wright stain is a combination of eosin and methylene blue dyes, while Giemsa stain is a mixture of eosin, methylene blue, and azure dyes. Giemsa stain is commonly used for staining blood smears to visualize parasites and bacteria, while Wright stain is used more for general cell morphology in blood and bone marrow specimens.
Which test is performed to determine blood type?
A complex testing for blood transfusion is called cross-matching. Otherwise, simple fingerpricks can also determine which blood type a person has. And if someone knows their biology well, they can put a sample of their own blood under a microscope and as long as they know what to look for, they can identify their blood type.
What is the name of blood test that says you are 'AA' or 'AS or'SS'?
The blood test is called a hemoglobin electrophoresis test, which is used to determine an individual's hemoglobin genotype. A result of 'AA' indicates normal hemoglobin, 'AS' indicates sickle cell trait (carrier), and 'SS' indicates sickle cell disease.
What type of blood is used for microhematocrit test?
capillary blood
How is the Giemsa stain used in the diagnosis of malaria?
The Giemsa stain is used in the diagnosis of malaria by staining the parasites in a blood sample, making them visible under a microscope. This helps healthcare providers identify the presence of malaria parasites in the blood, aiding in the accurate diagnosis of the disease.
What is secondary stain?
A secondary stain is Methylene blue. This type of stain is used in a acid fast staining. This type of staining test can determine medical conditions such as tuberculosis.
What are 3 possible causes of false positive reactions with presumptive screening test for blood?
Apply a solution of the chromogen to a sample of the suspected material/stain followed by addition of the oxidizing agent. a rapidly developing color constitutes a positive test; used to determine if blood is present.
What type of test is used by serologist to determine animal or human blood?
The Precipitin test distinguishes between human and animal blood.
Is the gram stain of significant importance in identifying hemolysis?
No, the Gram stain is primarily used to differentiate bacteria based on their cell wall structure (Gram-positive vs. Gram-negative). Hemolysis is a test used to determine the ability of bacteria to lyse red blood cells, which can provide information on the pathogenicity of the organism.
What is a precipitin test used for?
A precipitin test is used to determine if someone has been exposed to a specific antigen by detecting the presence of antibodies in their blood. This test is commonly used to diagnose certain infections or to confirm exposure to allergens.
What is the diagnostic test that determines the amount of glucose in the blood?
The diagnostic test used to determine the amount of glucose in the blood is called a blood glucose test. This test measures the concentration of glucose in a blood sample obtained through a finger prick or from a vein in the arm. It is commonly used to diagnose and monitor conditions such as diabetes and hypoglycemia.
Wrights stain or other stains?
Wright's stain is a Romanowsky stain used in medical laboratories to differentiate blood cells for microscopy. Other stains used for blood cell differentiation include Giemsa stain, Leishman stain, and Hematoxylin and eosin stain. Each stain has specific applications and staining properties.
Which blood test may confirm infectious mononucleosis?
A mononucleosis spot (or Monospot) test is a blood test used to determine whether or not you are infected with the Epstein-Barr virus, which is the organism that causes infectious mononucleosis.
What blood test is used for heparin?
The most common test to monitor heparin therapy is the activated partial thromboplastin time (aPTT) test. This test measures the time it takes for blood to clot and helps determine if the level of heparin in the blood is within the therapeutic range.
Can you tell how old a blood stain is?
No, the age of a blood stain cannot be determined solely by looking at it. Factors like environment, fabric type, and blood volume can affect the appearance of a stain. In forensic investigations, chemical testing and analysis are used to estimate the age of a blood stain.
What blood test to determine kidney function by measuring the level of nitrogenous waste in the blood?
The blood test used to determine kidney function by measuring the level of nitrogenous waste in the blood is called the Blood Urea Nitrogen (BUN) test. Elevated levels of BUN can indicate impaired kidney function, as the kidneys are responsible for filtering urea, a waste product formed from protein metabolism. This test is often used in conjunction with other tests, such as serum creatinine, to assess overall kidney health.
What test is used to determine therapeutic range for heparin?
blood test are done to find out if you are having a heparin overdose.
