The basic design of a synthetic aperture radar system can be enhanced to collect more information. Most of these methods use the same basic principle of combining many pulses to form a synthetic aperture, but may involve additional antennas or significant additional processing.
Total is a combination of direct and indirect bilirubin. Typically, you'll get results for direct and total bilirubin. Normal results for a bilirubin test are 1.2 milligrams per deciliter (mg/dL) of total bilirubin for adults, and usually 1 mg/dL for those under 18. Normal results for direct bilirubin are generally 0.3 mg/dL. These results may vary slightly from laboratory to laboratory. Normal results may be slightly different for women and children, and results may be affected by certain foods, medications or strenuous exercise.
A bilirubin test is used to detect an increased level in the blood. It may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, and blockage of the bile ducts.Bilirubin is an orange-yellow pigment, a waste product primarily produced by the normal breakdown of heme.f conjugated (direct) bilirubin is elevated more than unconjugated (indirect) bilirubin, there typically is a problem associated with decreased elimination of bilirubin by the liver cells. Some conditions that may cause this include: 1  Viral hepatitis. 2  Drug reactions.
