Allergy tests

Allergy tests indicate a person’s allergic sensitivity to commonly encountered environmental substances.

Alopecia:

 Alopecia simply means hair loss (baldness). Hair loss occurs for a great many reasons—from pulling it out to having it killed off by cancer chemotherapy. Some causes are considered natural, while others signal serious health problems. Some conditions are confined to the scalp. Other.- reflect disease throughout the body. Being plainly visible, th: skin and its components can provide early signs of disease elsewhere in the body. Oftentimes, conditions affecting the skin of the scalp will result in hair loss. The first clue to thebaldness (alopecia totalis), patchy bald spots, thinning, or hair loss confined to certain areas. Also a factor is the condition of the hair and the scalp beneath it. Sometimes only the hair is affected; sometimes the skin is visibly diseased as well.
Alpha-fetoprotein test: The alpha-fetoprotein (AFP) test is a blood test that is performed during pregnancy. This screen¬ing test measures the level of AFP in the mother’s blood and indicates the probability that the fetus has one of several seri¬ous birth defects. The level of AFP can also be determined by analyzing a sample of amniotic fluid. This screening test can¬not diagnose a specific condition; it only indicates the increase of risk for several birth defects. Outside pregnancy, the AFP test is used to detect liver disease, certain cancerous tumors, and to monitor the progress of cancer treatment.

Alpha, -adrenergic blockers: 

Alphaadrenergic blockers are drugs that work by blocking the alpha 1-receptors of vascular smooth muscle, thus preventing the uptake of catecholamines by the smooth muscle cells. This causes vasodilation and al¬lows blood to flow more easily.
