The best use of CEA is as a tumor marker, especially for cancers of the gastrointestinal tract. When the CEA level is abnormally high before surgery or other treatment, it is expected to fall to normal following successful surgery to remove all of the cancer.he most frequent cancer which causes an increased CEA is cancer of the colon and rectum. Others include cancers of the pancreas, stomach, breast, lung, and medullary carcinoma of the thyroid and ovarian cancer.
Screen refresh rate is the number of times an image on any type of monitor or television is reconstructed per second. This is measured in hertz.. (Hz) For example, a TV witâ¦h a refresh rate 60Hz, reconstructs the image you're seeing 60 times every second. Basically, the higher the refresh rate on a tv, the representation of motion will be smoother, and the image will flicker less.
----------------------------. I think this explains it far better than I can. The TV's refresh rate is the Hz value. So, for instance, if it is 120 Hz, then it is native 120 Hz (and will always run at 120 Hz). If you have 24p active, the TV will display each frame 5 or 10 times in accordance with the refresh rate as 120 and 240 are both divisible by 24 (where as 60 is not-this is where you get into 3:2 pull downs with 60 Hz TVs). Motionflow is another animal altogether.
