The examination for the detection of congenital anomalies is referred to as either detailed ultrasound study or targeted imaging for fetal anomalies (TIFFA) 3, 4 In such examinations, a variety of fetal anatomic views (âtargetsâ') are specifically sought after and imaged by experienced ultrasonographers.
Turbidity is measured in NTU: Nephelometric Turbidity Units. The instrument used for measuring it is called nephelometer or turbidimeter, which measures the intensity of light scattered at 90 degrees as a beam of light passes through a water sample.
To do this, you need to quantify the amount of growth by comparing theturbidity. Carefully shake all 5 tubes and holding them up to the light, determinethe amount of growth based on the following criterion.+1 very light turbidity+2 medium turbidity+3 heavy turbidity (o ptimal temperature)2.
