Usually, a red color indicates a flow toward the ultrasound transducer, while blue indicates a flow away from the transducer. Based on the display, doctors can evaluate blood flow to the umbilical arteries, umbilical veins, or other organs such as heart and brain. Nonstress test
Nonstress test (NST) is a type of electronic fetal monitoring that uses a cardiotocograph to monitor fetal heartbeat, fetal movement and mothers contraction. NST is typically monitored for at least 20 minutes. Signs of a reactive (normal) NST include a baseline fetal heart rate (FHR) between 110 and 160 beats per minute (bpm) and 2 accelerations of FHR of at least 15 bpm above baseline for over 15 seconds. Vibroacoustic stimulation and longer monitoring may be needed if NST is non-reactive. Biophysical profile
A biophysical profile is a noninvasive procedure that uses the ultrasound to evaluate the fetal health based on NST and four ultrasound parameters: fetal movement, fetal breathing, fetal muscle tone, and the amount of amniotic fluid surrounding the fetus. A score of 2 points is given for each category that meets the criteria or 0 points if the criteria are not met (no 1 point). Sometimes, the NST is omitted, making the highest score 8/8 instead of 10/10. Generally, a score of 8/10 or 10/10 is considered a normal test result, unless 0 points is given for amniotic fluid. A score of 6/10 with normal amniotic fluid is considered equivocal, and a repeated test within 24 hours may be needed.
Adults:
Body Mass Index (BMI) is the quotient between weight and height squared (kg/m2). An individual with a BMI < 18.5 is regarded as a case of wasting. Percent of body weight lost (At Tufts, an unintentional loss of 6% or more in 6 months is regarded as wasting)

Treatment and prevention
Antiretrovirals and anabolic steroids have been used to treat HIV wasting syndrome. Additionally, an increase in protein-rich foods such as peanut butter and legumes (dried beans and peas) can assist in controlling the loss of muscle mass. See also
