The Center for Biologics Evaluation and Research (CBER) regulates allergenic products. There are currently two types of allergenic products licensed for use: allergen patch tests and allergenic extracts. Allergen patch tests are diagnostic tests applied to the surface of the skin. Patch tests are used by physicians to determine the specific causes of contact dermatitis, and are manufactured from natural substances or chemicals, such as nickel, rubber, and fragrance mixes, that are known to cause contact dermatitis.
Allergenic extracts are used for the diagnosis and treatment of allergic diseases such as allergic rhinitis ("hay fever"), allergic sinusitis, allergic conjunctivitis, bee venom allergy and food allergy. Allergenic extracts are injectable products that are manufactured from natural substances, such as molds, pollens, insect venoms, animal hair, and foods, known to elicit allergic reactions in susceptible individuals. Food extracts are only used to diagnose food allergies, but other allergenic extracts may be used for both diagnosis and treatment of allergic disease.
Allergenic extracts are currently manufactured in two forms: standardized and unstandardized. Prior to release standardized allergenic extracts are compared to US reference standards for potency. CBER maintains these reference standards and distributes them to manufacturers. There are currently 19 standardized allergenic extracts. Extracts for which there are no US reference standards are called unstandardized extracts.

It is an infection or disease passed from person to person through sexual contact.
How many people have STDs?
The United States has the highest rates of STDs in the industrialized world. In the United States alone, about 19 million new infections are estimated to occur each year. Women suffer more frequent and more serious complications from STDs than men.
How do you get an STD?
You can get and pass STDs through vaginal, anal, or oral sex. Trichomoniasis can also picked up from contact with damp or moist objects such as towels, wet clothing, or a toilet seat, if the genital area gets in contact with these damp objects. Some STDs cause no symptoms. But STDs can still be passed from person to person even if there are no symptoms.

Cancer is a disease in which certain body cells don't function right, divide very fast, and produce too much tissue that forms a tumor. Ovarian cancer is cancer in the ovaries, the female reproductive organs located in the pelvis. The ovaries make female hormones and store eggs that, if fertilized by sperm, can develop into a baby. Women have two ovaries, one on each side of the uterus. Tumors found in the ovaries may be non-cancerous tissue growths (cysts) or cancerous growths that may spread to other parts of the body.
