What are The blood proteins A and B?
The blood proteins A and B are antigens found on the surface of red blood cells that determine blood type. Individuals with blood type A have A antigens, while individuals with blood type B have B antigens. Blood type AB individuals have both A and B antigens.
If a patient is a 28 year old male who is trying to identify a cause for his infertility. Chromosomes were obtained from nucleated cells in the patient's blood. what is his karyotype?
To determine the karyotype of a 28-year-old male, one would typically expect to see 46 chromosomes, including one pair of sex chromosomes. In males, the sex chromosomes are typically represented as XY, indicating the presence of one X and one Y chromosome. Therefore, if no abnormalities are present, the karyotype would be 46,XY. However, if there are any known issues or abnormalities, further genetic testing would be needed to provide a specific karyotype.
What are the equipments use in physical examination?
Some common equipment used in a physical examination includes a stethoscope for listening to heart and lungs, a blood pressure cuff for measuring blood pressure, an otoscope for examining the ears, an ophthalmoscope for examining the eyes, a reflex hammer for testing reflexes, and a thermometer for measuring temperature.
What is the first thing geneticists do in order to begin to analyze a human karyotype?
The first thing geneticists do in order to analyze a human karyotype is to obtain a sample of cells, usually through a blood test. They will then culture the cells in the lab, stop the cells in metaphase of mitosis, stain the chromosomes, and take a microphotograph to examine the chromosomes under a microscope.
What can be determined from a karyotype?
Analysis of a karyotype determine how many chromosomes are in blood cells. It also determines if there are any missing or extra chromosomal material that are indicators of genetic disorders such as downs syndrome.
How does Babesiosis get diagnosed?
Babesiosis can be diagnosed by examining a blood sample microscopically and detecting the presence of Babesia microti within the blood cells
How is relapsing fever diagnosed?

How is substance abuse and dependence diagnosed?
With the person's permission, substance use can also be detected by examining an individual's blood, urine, or hair in a laboratory. Drug testing is limited by sensitivity, specificity, and the time elapsed
What would happen if you tried to make a karyotype from isolated mature red blood cells?
You must be in genetics lab... Red blood cells do not have a nucleus therefore a karyotype cannot be assembled. The chromosomal preparations cannot be performed on the red blood cells. Thus, the reason they use white blood cells.
What is the way Bacteremia is diagnosed?
Bacteremia is diagnosed by culturing the blood for bacteria
How is Waldenstrom's macroglobulinemia diagnosed?
Since many individuals with WM have no symptoms, the initial diagnosis may result from blood tests that are performed for some other purpose.
What three questions should the investigator answer when examining an apparent dried blood stain?

by a blood test
How is lymphoma cancer diagnosed?

How is HIV infection diagnosed and treated?
You get diagnosed with a blood test, and a personalized protocol is placed as a perscription.
How is sickle cell diagnosed?
Sickle cell is diagnosed by a simple blood test called hemoglobin electrophoresis. This analyzes the blood and points out abnormal cells.
