Many of us read in inquiries about laboratory tests during pregnancy. We carry out laboratory tests for diagnostic purposes: most of the time the mother - but often the fetal condition - is checked.

The first task to be performed in the case of a pregnancy test for the detection of pregnancy is the first laboratory test. For this purpose, cells are removed from the cervical surface and from the cervical canal (mostly plastic with properly shaped shells) and smeared on a slide plate. With the help of this filter, you can recognize the cerebral processes, especially malignancies, in the early stages, but you can also brighten up your inflammatory conditions, which are important in pregnancy. At the same time, the vagina is also sent to a lab where the staining of the vagina is treated with proper staining to prevent serious pregnancy-related events by detecting vaginal infections. The vaginal examination should be performed 3 times during pregnancy without complaints. The first bleeding occurs after pregnancy is detected. For this, check the ъn. routine blood count parameters: the number, the rate (of blood cells, white blood cells, blood cells), the rate at which the blood elements of the blood The patient's blood group, Rh factor, and Rh negative mother are tested for the presence of antibodies. In all cases, a blood test (lues or syphilis) is also performed (multiple screening tests are useful, most often VDRL or Wassermann screening). Unreasonable extensions of laboratory examinations are medically and budget-friendly. Pregnant women urine is tested at each application for purulent, white, sugar, and acetone. In physiological pregnancy, routine maternal blood flow should be performed three times throughout the pregnancy.We should test for alpha-phytoprotein (AFP) from maternal blood at 16 weeks of gestation. AFP is a protein produced by the liver of the fetus, which, under normal conditions, is only released in very small quantities into the mother's circulation. Certain abnormalities in the fetus, primarily the body itself. in the case of oyster closure disorders (fistulae, open spine, abdominal closure disorders), AFP reaches the mother in large quantities, thus increasing the value. Lower AFP values ​​may indicate fetal chromosome aberrations. Nowadays, the AFP values ​​are reported in most laboratory-standardized values. The default value is 1.0 MoM (MoM - Multiple of the Median). It is considered normal between 0.7-2.5 MoM. It is important to emphasize the need for an AFP examination: lung values ​​do not necessarily mean sick fetuses, but justify the need for further examinations (ultrasound, genetic examinations if necessary). It is very important that AFP is removed at the 16th week of loading, and only then can a reliable evaluation of the values ​​obtained be obtained with sufficient accuracy. At week 16, you will also have a hepatitis B screening test (HbsAg test) at the same time as your AFP screening. If this is not the case, immunization of the newborn is mandatory in all cases after birth.
We carry out a laboratory screening test in the second trimester of pregnancy to check sugar metabolism. This is the first step in determining fasting blood glucose. When this is normal, a sufficient amount of carbohydrate (in the form of a special breakfast or sugar solution) is injected into the body and the blood glucose level is readjusted after 1 hour. Sugar intake responds by releasing enough insulin from the pancreas so that the blood sugar levels increase only marginally. In the case of inadequate insulin secretion, the blood glucose levels rise abnormally, so that the second screening test results in abnormally high results. Such is ъn. "single-point" sugar load test is just a screening test: you need more blood glucose testing to correct the diagnosis of gestational diabetes, with repeated blood tests.
