Blood is one of the most important substances in our body. By its state, various pathologies can be identified (including at the very early stages of development). Donate blood correctly. This may be required if necessary to undergo a general or special examination. Donors also undergo thorough preparation before the procedure. What diet is prescribed to the patient before blood donation and other tests will be discussed later.
Why is diet important?
Why diet before donating blood? The answer to this question is simple. If you do not adhere to the recommendations of doctors, it is incorrect to prepare for the procedure, the blood changes its appearance. Chylosis develops in it. This is a special condition of blood serum. Chilez interferes with proper diagnosis. If the blood is donated, its condition should be perfect. Otherwise, it cannot be used for transfusion.
Chilosis is a condition of blood serum in which there is a high content of particles of fat. Such blood is also called "milk". During the analysis or during the transfusion, it may be necessary to divide it into several parts. In this case, "fat" blood becomes like sour cream. It takes on a white hue and thickens.
Blood components cannot be isolated from such serum. It cannot be used to perform analyzes. It is absolutely impossible to transfuse such blood to another person. Therefore, a proper diet is an important procedure during the preparation of blood donation.
General (clinical) analysis
What diet to follow before donating blood? It depends on the type of analysis itself or subsequent manipulations with the substance. Diet may be slightly different because of this. One of the frequently performed types of diagnosis is clinical analysis. It provides an opportunity to establish the level of hemoglobin, the composition of blood cells, as well as ESR.
Such an analysis is prescribed during a routine examination, during pregnancy. Also, in the presence of certain diseases or suspicions of the development of certain pathologies, the doctor prescribes this analysis.
It is worth noting that there are no strict training rules before conducting this diagnosis. Some doctors recommend donating blood before eating. Therefore, most often it is carried out in the morning. A light breakfast is allowed. It should not contain dairy products, sweet, fried, greasy and spicy. You can drink clean water right up to the analysis itself. It should be clean, non-carbonated, without additives and flavorings.
Biochemistry
Special preparation requires biochemistry. The diet before giving blood for tests of this type will be more stringent than in the previous case. Otherwise, you may get the wrong result. Blood biochemistry allows you to determine the condition of many systems, organs. The preparation will be quite lengthy.
Three days before the procedure, you need to abandon physical activity. Emotional stresses are also unacceptable. Also, at least 3 days before biochemistry, you can not drink any alcoholic beverages.
They donate blood necessarily on an empty stomach. Dinner should be no later than 20: 00-21: 00 hours. Before this, it is impossible to undergo diagnostic, physiotherapeutic procedures. You should also refuse to take medications. It is necessary to exclude the intake of fatty, sweet, fried foods. If uric acid levels are determined during biochemistry, offal (liver, kidneys), fish, meat, tea and coffee are excluded from the diet a few days before the examination.
Cholesterol
Diet before donating blood for cholesterol should also be strict. This is a fairly common analysis. Today it can be taken in almost any laboratory in a private or public clinic. To get an accurate result, you need to follow a series of simple recommendations.
In this case, dinner should be done 12-14 hours before the procedure. Therefore, the analysis is given in the morning. Dinner should be no later than eight o’clock in the evening.
72 hours before the examination, you need to abandon the use of fatty, fried foods. Alcohol and smoking are also banned. It is necessary to stop taking dietary supplements. The examination is prescribed by a doctor. If a person takes any medication, he must inform his supervising medical professional about it.
Sugar
The diet before donating blood for sugar depends on the purpose of the examination. This is reported by the doctor. The procedure is carried out to control sugar levels at different stages of digestion. This allows you to identify the presence of a disease such as diabetes mellitus of the first and second type, to monitor the effectiveness of therapy in patients.
In this case, an examination may be required both on an empty stomach and after a meal. The doctor should tell about the diet. In some cases, you need to take an analysis on an empty stomach. In this case, you need to have dinner at least eight hours before the procedure. In this case, it is not allowed to drink tea or juice during this period. You can drink clean, still water without additives.
If control should be carried out after a meal, this should be done one hour or an hour and a half before blood donation (not earlier). The choice of preparation depends on the diagnostic technique. The doctor should tell in detail about all the nuances.
Hormones
What diet before donating blood for hormones will get a reliable result? This type of diagnosis is always performed on an empty stomach. In the evening you will need to eat until 20:00 (10-11 hours before the examination). It is forbidden to drink tea, coffee or juice. You can drink clean water.
Exceptions to this rule are blood tests for hormones such as C-peptide or insulin. In this case, you will need to eat 2 hours before the examination. The doctor who appoints the examination should inform the patient about all the intricacies of preparation. Otherwise, the result will be incorrect.
If you are tested for thyroid hormones, you need to exclude products that contain iodine in a couple of days. These include seafood, fish or iodized salt. Donating blood to prolactin, you need to have time to get to the laboratory no later than 120 minutes after waking up. You can’t rush. Before taking the test, the patient should sit quietly for 20 minutes. The day before diagnosis, you need to go to bed no later than 22:00. The result of the examination depends on this.
Donation
The diet before donating blood is crucial. This allows you to get material that meets all standards. Blood that will be used for transfusion should not harm the health of the patient. Therefore, before transfusion, the blood of the donor is carefully monitored. Diet allows her to comply with existing regulations.
Improper nutrition significantly reduces blood quality. Plasma chilosis is unacceptable. Do not transfuse thick blood, which, due to the high content of particles of fat, becomes unsuitable for transfusion.
A diet before donating blood will not be difficult for a person. It is just a healthy diet. A number of foods will need to be excluded from the diet. The doctor can find out a detailed list of products that are forbidden to take before the procedure. These rules will need to be followed for several days.
What should be excluded from the diet?
A donor diet before blood donation is prescribed to a person at least two days before the procedure. It is recommended to stick to it even earlier. Three to four days before blood donation, a person should give up a number of food products, such as:
- The eggs.

These recommendations should be followed by those people who will donate blood for sugar, biochemistry. Sometimes it’s useful to just do fasting days, excluding the products listed from the menu. You can not take any medications, smoke. Such a diet is useful not only for the person who receives blood transfusion, but also for the rehabilitation of the donor himself.
What do donors need?
The diet before donating blood for transfusion contains a number of products that will be useful to both the donor and the patient. 3 days before the procedure, lean meat, especially beef (helps increase hemoglobin levels) should be included in the diet. You can also eat skinless chicken meat.
The diet can be supplemented with fish of low-fat varieties. Be sure the food should contain a large number of vegetables (except for beets). You can eat bread from wholemeal flour, bagels (drying). The diet includes various cereals on the water. You can periodically eat pasta. Do not add oil to them.

Some more recommendations
To make the procedure easy for the donor, and the body quickly recovered after blood donation, two weeks prior to its implementation, you must also adhere to a special diet. It is slightly different from previous recommendations. Some products are acceptable at this time. Their components are involved in the function of hematopoiesis.
In the diet 14 days before the procedure, you need to increase the number of foods rich in iron. These include fish, meat (beef) and poultry. You also need to regularly eat beans, raisins, prunes, spinach.
Providing enough iron during preparation is crucial. It is necessary to increase hemoglobin in the blood. If iron and other vitamins and minerals that are involved in the function of hematopoiesis are not enough, after the procedure, the donor may develop signs of iron deficiency anemia. It is also worth reducing the number of coffee receptions, products with a significant content of calcium, as well as tea. They interfere with the processes of assimilation of iron.
Diagnosis of blood in the stool
Another method for the diagnosis of various diseases of the gastrointestinal tract is the analysis for the presence of occult blood in the feces. It allows you to identify some pathologies and diseases in the digestive tract. In this case, a diet is also required before giving stool for occult blood.
The presented analysis is prescribed for frequent pain in the abdominal cavity, heartburn, nausea. With frequent constipation or other disorders of the stool, this analysis is also performed. If a person loses weight for no reason, his appetite is reduced, the doctor prescribes the type of diagnosis presented.
If a preliminary examination revealed anemia, in some cases, feces for hidden blood are also given. The analysis allows you to determine the presence of peptic ulcer, polyposis, ulcerative colitis, as well as intestinal tuberculosis in the body. Diet before taking the test is prescribed for 3 days. If the body has parasitic diseases, this diagnostic method can be prescribed to assess the degree of damage to the intestinal mucosa.
What to exclude from the list of dishes?
A diet before stool donation for occult blood involves the exclusion of certain foods 3 days before the procedure. These include fish, meat dishes, green vegetables, and liver. You can’t eat white beans and spinach. You should temporarily abandon beets, apples and bell peppers. Pomegranate is also ruled out. Horseradish and tomatoes, blueberries are removed from the diet.
