You will be realized by the measurement of the uterine height, useful practice to evaluate the growth delay intraútero. There are risk factors for the delay of the growth intraútero:

1. Important illnesses.
2. Low maternal size.
3. Under weight pregestacional and lacking in profit in weight in the gestation.
4. Habit tabáquico.
5. Addiction to the alcohol and other drugs.
6. Personal precedents of fetal death or of delay of the growth intaútero.

The tests in this occasion will be:

1. Analysis of urine and blood: Conditions that might be harmful to the health of his baby (for example, hepatitis B, syphilis and other infections of sexual transmission).
   • Antibodies that show if it is immune or not to the German measles (German measles) and to the chicken pox, illnesses that can cause birth defects if the mother contracts them for the first time during the pregnancy
   • Anemia (under inventory of red globules), what might do that she feels particularly tired and, in some cases, to increase his risk of premature childbearing
   • Bacteria in the urine. Up to 10 per cent of the pregnant women it has bacteria in the urine, which indicates an infection in the urinary tract. The majority does not present symptoms but even an asymptomatic infection can propagate and come to the kidneys, where it can represent a serious risk for the mother and the baby. The infections of the urinary tract talk each other with antibiotics that are sure both for the mother and for the baby
   • Sugar in the urine. This can be a diabetes sign. It is possible that his doctor asks him that additional tests should be realized if sugar is detected to him in the urine.
   • Protein in the urine. This can indicate an infection of the urinary tract or, in a later stage of the pregnancy, a condition related to the pregnancy that arterial high pressure includes. It is possible that his doctor asks him that additional tests should be realized if it detects protein in the urine.
2. Ultrasound scan to verify that the fetus and his small ecosystem are normal. The ultrasound scan, ultrasonography or ecosonografía is a procedure of imagenología who uses the echoes of an ultrasound emission directed on a body or object as data source to form an image of the organs or internal masses with diagnosis ends. A small instrument "similar to a microphone" called transducer expresses ultrasound waves. These sonorous waves of high frequency transmit towards the area of the low body study, and his echo is received. The transducer gathers the echo of the sonorous waves and a computer turns this echo into an image that appears on the screen of the computer. The ultrasound scan is a very easy procedure, in which radiation is not used, although it usually realize in the radiodiagnóstico service, and that's why it is used often to visualize fetuses that are forming. On having surrendered to an ultrasound scan examination, the patient simply goes to bed on a table and the doctor moves the transducer on the skin that is on the part of the body to be examined. Earlier it is necessary to place a gel on the skin for the correct transmission of the ultrasounds. It is not invasive test (not dangerous) across which you will see your son on a screen. Normally after 8th week is when it is possible to appreciate. Across this test there can be calculated the fetal age and his morphology (hands, feet, sexual organs...)
