typing

 [tīp´ing]
in transplantation immunology, a method of measuring the degree of organ, solid tissue, or blood compatibility between two individuals, in which specific histocompatibility antigens (such as those on leukocytes or erythrocytes) are detected by means of suitable isoimmune antisera.
blood typing (typing of blood) determining the character of the blood on the basis of agglutinogens in the erythrocytes; see also blood group.
phage typing characterization of bacteria, extending to strain differences, by demonstration of susceptibility to one or more races (a spectrum) of bacteriophage; widely applied to staphylococci, typhoid bacilli, and other organisms for epidemiological purposes.
tissue typing identification of the human leukocyte antigens of the donor and recipient of a transplant or transfusion; see also tissue typing.

typing

in transplantation and transfusion immunology, a method of measuring the degree of organ, solid tissue, or blood compatibility between two individuals, in which specific histocompatibility antigens (e.g. those present on leukocytes) or other cell surface antigens, e.g. red blood cell antigens, are detected by means of suitable immune serum.

blood typing
determining the antigenic determinants present on the surface of red blood cells by using specific antibodies (typing serums). See also blood group.

Patient discussion about typing

Q. how many types of cancer are they?

A. There are over 200 different types of cancer. You can develop cancer in any body organ. There are over 60 different organs in the body where you can get a cancer.

Each organ is made up of several different tissue types. For example, there is usually a surface covering of skin or epithelial tissue. Underneath that there will be some connective tissue, often containing gland cells. Underneath that there is often a layer of muscle tissue and so on. Each type of tissue is made up of specific types of cells. Cancer can develop in just about any type of cell in the body. So there is almost always more than one type of cancer that can develop in any one organ.

Q. What types of arthritis are there? I am familiar with several types of arthritis, for instance R.A or ostheoarthritis. Are there more types?

A. Arthritis is a symptom that can occur on its own as part of a known disease such as RA, osteoarthritis or Gout, and can also happen as a part of other complex of symptoms involving the joints in other diseases such as: Crohn’s disease, ulcerative colitis, psoriasis and so on. Other diseases can mimic arthritis for instance: osteoporosis or multiple myeloma.

Q. Types of Bipolar I like to know that how many types of bipolar is there and what are its symptoms? Can any one please explain?

A. The DSM-IV (bible of psychological disorders) recognizes two disorders within the category of Bipolar disorders. Bipolar I Disorder is the characteristic cycling of depressive lows and manic highs (the extent and length of these extremes differ from person to person). Bipolar II disorder is cycling between depression and less intense hypomanias. So in a way, Bipolar II is less fun than Bipolar I. Manias and Hypomanias are not just being really happy. They are merely a period of intense energy and activity. The patient often has little control over what they say or do during this period.
There is something in Bipolar disorder called a "Mixed Episode". They are not very common but this is a very distressing period in which a person experiences symptoms from both a mania and a depression at the same time. Dark, disturbing thoughts and intense anxiety and lowered inhibitions--even panic attacks. In the words of my professor: "Mixed episodes suck".
