Credit Sweep. Share. DEFINITION of 'Credit Sweep'. Also known as an automated credit sweep, this term refers to an arrangement between a bank and a customer (usually a corporation) whereby all idle or excess funds in a deposit account are used to pay down short-term borrowing under a line of credit.
A prolactin test measures the amount of this hormone in the bloodstream. In a woman who breastfeeds, the nursing baby's demand for milk actually controls the mother's supply. When a baby sucks at the breast, the woman's pituitary gland releases more prolactin into her blood, increasing her milk production.
A number of otherwise healthy people have elevated prolactin levels because some of the prolactin in their blood is in a different form called macroprolactin. Macroprolactin is prolactin that is bound to a protein (immunoglobulin), is not active in the body, and does not indicate the presence of disease. If an elevated prolactin is found, further laboratory tests may be done to make sure that this is not due to macroprolactin. ^ Back to top.
