Maybe: ask doctor.: Your sleep-wake cycle impacts many different hormones. If you are usually a night shift worker, and keep the same sleep-wake cycle every day, it's not an issue; if this shift isn't part of your usual routine it may well interfere with accurate test results. Please ask the doctor who ordered the test if a single night shift before the draw will impact the results enough to consider waiting.
