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.
If your prolactin levels are high, the test may be repeated in the early morning after an 8-hour fast. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
