Recent data indicate that h-hCG is similar to hCG itself, although its measurement in maternal urine may improve the performance of the established serum marker combinations. Research into other possible second trimester screening markers has included studies on the maternal urine and serum levels of an hCG variant, hyperglosylated hCG (h-hCG invasive trophoblast antigen). hCG: human chorionic gonadotropin is a hormone produced within the placenta. In fact, from reading the description of StormLab on their web site, it works exactly the same way as GRLevel3 in that it downloads small packets of processed radar data from the NWS and then it generates images and other products to display on your computer screen.
AFP: alpha-fetoprotein is a protein that is produced by the fetus. StormLab gets their data from the National Weather Service, just like everybody else, so there is a delay. Extensive weather information GRLevel3 can help you find out any temperature shifts or rain forecasts for any zone on the globe.

Quality control parameters for inhibin A measurement are acceptable and are monitored through the proficiency testing program administered by the College of American Pathologists. Also Known as Triple Test, Multiple Marker Screening and AFP Plus The triple screen test is a maternal blood screening test that looks for three specific substances: AFP, hCG, and Estriol. Furthermore, you can place a home marker on your current location and observe various changes that occurred there. Inhibin A, the newest addition to second trimester serum screening, is an alpha-beta subunit hormone of placental origin, and is measured using a monoclonal two-site ELISA validated for use in prenatal screening. With this combination, a detection rate of 80% at a 5% false positive rate is achieved. The multiple marker combination with the highest screening performance currently available is alpha-fetoprotein (AFP), unconjugated estriol (uE3), human chorionic gonadotropin (hCG), and inhibin A, together with maternal age (so-called quad marker test). You have to learn to anticipate what the next volume scan is going to show you.Prenatal screening for Down syndrome in the early second trimester with multiple maternal serum markers has been available for more than 15 years. One thing to keep in mind about these programs.There is always a lag between what you see in the radar image and what's happening in real life. I run GRLevelX in four-panel mode on a wide-screen monitor so I can see Base Reflectivity, Storm Radial Velocity, Tops, and VIL all on the screen at once. And, if I remember correctly, hover over a warning in the Warnings window and a pop-up will appear with the text of the warning. In the Warnings window, double click on a warning and the program will jump to the radar site nearest the warning. Works seamlessly with iPads, desktop computers, and laptops.

Somewhere in the forums, I found out how to import Tiger map data so I can get street-level maps under my radar images.Ī couple of neat features. I learned a lot about the program from reading the forums. Once you register, you can get access to the registered users only forums. Also, check the forums on the GRLevelX web site. You kinda have to poke around on the menus and see what happens. There's not a lot of documentation for the program. GRLevel3 also has provisions for hooking up a GPS receiver so you can plot your position while mobile. You can then use the right click menus to measure the distance of something from the dot. Click to expand.The previous post will tell you how to make a dot at your home location.
