How to prepare for a blood test
The doctor during the Middle Ages had to rely on their senses: touch, hearing, sight, taste, smell. Fortunately, modern doctors are helped by additional diagnostic methods, one of which is certainly a blood test.
All laboratory tests of blood, regardless of whether a finger is taken from the finger or from a vein, are given on an empty stomach. On the eve, starting with breakfast, from the diet is excluded fat, fried foods and alcohol. Food fats, assimilated by blood, can change its biochemical characteristics. And this can complicate the diagnosis of diseases of internal organs. Remember that fats make blood viscous, less fluid, so even when taking blood from the finger, difficulties may arise. Before analyzing blood, food should not be taken for at least 8 hours. Juice, tea, coffee, especially with sugar, is also a meal, so be patient.
The morning of the day when the blood test is scheduled, you can not only drink and eat, but also smoke! Some doctors believe that even cleaning teeth at that time is undesirable. Common sense suggests that you can still clean your teeth, but not for long, so as not to cause active salivation.
The results of laboratory diagnostics are also influenced by the intake of many medications. In this regard, whenever possible, before the research, limit the intake of non-essential medicines and consult your doctor. Also, blood should not be taken after physiotherapy, rectal examination, radiography.
Some indicators of blood can be affected by previous physical activity - fast walking, running, climbing the stairs. Therefore, to reduce the negative impact of these factors, rest 10-15 minutes before the procedure in the waiting room and try to calm down. In anticipation of its turn to diagnose diseases of internal organs do not need to shake with horror. Fear of the procedure can also affect some blood counts. If you have to draw blood from your finger, it's best to make sure that your fingers are warm and warm. Otherwise, the lab technician will torture you with violent blood sucking, which does not want to flow from the cold finger.
How to prepare for urine analysis
Laboratory analysis of urine is one of the indispensable conditions for the accurate diagnosis of diseases of internal organs. To collect urine for analysis, the most important condition is the observance of intimate hygiene before filling the cherished vessel. Otherwise, the analysis will be contaminated. Postpone the day of the urine test, if you have a period. If you take any medications, tell your doctor, because some drugs can influence the analysis. There are no restrictions in the diet, but it is not worthwhile to lean on mineral water - it changes the reaction of urine.
How to prepare for ultrasound
The third most common instrumental method of diagnosis - ultrasound (ultrasound) of internal organs. Undoubted advantages of ultrasound research include, first of all, its safety for the patient. It is proved that ultrasound does not have significant harmful effects on the body. Therefore, if the doctor needs to clarify the diagnosis, the ultrasound procedure without unnecessary fears can always be repeated anew. The uniqueness of this method also lies in the fact that within the framework of a single visit to a doctor, it is possible to conduct research on many systems and organs.
Ultrasound of the abdominal cavity organs. The abdominal cavity is, in fact, a closed bag, in which the soft internal organs are compactly located: the liver, stomach, spleen and intestine. Moreover, the less content in the intestine, especially gases, the more accurate and easier to conduct ultrasound. Therefore, the entire preparation for ultrasound research is reduced to adherence to a certain food regime. 2-3 days before the study, all foods that cause fermentation are excluded from the diet: black bread, milk, cabbage (both fresh and sauerkraut), peas and beans, beer. All these days, take after breakfast, lunch and dinner 2-3 tablets of activated carbon.
Since ultrasound of the abdominal cavity is performed strictly on an empty stomach, one can not drink anything on the day of the study and eat. Coffee and tea are strictly excluded. These limitations are also connected with the fact that one of the studied objects is the gallbladder, which is reduced even from one sip of hot water. In this case, accurate instrumental diagnosis of internal organs is questioned. If before the examination to provoke it to reduce, the doctor will not be able to correctly estimate its size.
Ultrasonic examination of pelvic organs. Female anatomy is such that the uterus with appendages somewhat changes its position depending on the degree of filling of the bladder. In this case, the ultrasonic shadow can be obtained clearly only if the bladder is well stretched by a large amount of urine. To do this, one hour prior to the study, you need to drink 1 liter of water and come to the study with a strong desire to visit the toilet. Prophylactic ultrasound examination of the uterus and appendages is best performed on the 5th-7th day of the menstrual cycle.
Ultrasound examination of mammary glands. Preventive examination of mammary glands is done on the 6th-8th day of the menstrual cycle. In other cases, the need for this study is determined by the doctor, regardless of the day of the cycle. To conduct ultrasound of the kidneys, thyroid gland special training is required.
For accurate laboratory and instrumental diagnosis of diseases of internal organs, the above rules must be observed.
