Can I donate blood tests during menstruation, why not

During menstruation I have many processes in the female body, affecting the composition of bioliquids. To find out whether you can donate blood during menstruation, it is necessary to know what are the important parameters for the diagnosis of distorted during this period. If the survey is not urgent, it is better to postpone the procedure until after the critical days. Otherwise, you need to preset the doctor aware of the beginning of the selection, that it is taken into account.

Can I donate blood during menstruation

There are studies which menstruation has absolutely no effect. Others, on the contrary, specifically appointed in the critical days. But is it possible to take specific blood test during menstruation, should check with your doctor.

In the event that certain studies can give false information, appointing their specialist should inform the woman. Optimal cycle time for such analyzes - from the 8th to the 15th day.

The general analysis

general analysis of blood research just before menstruation and the first few days will show an increased hemoglobin and red blood cells. Then indicators fall much, making the result invalid.

Declining levels of leucocytes, hematocrit, thrombocytes. The value of the erythrocyte sedimentation rate (ESR or), in contrast, will be overstated.

For a general analysis can donate blood only in emergency situations, at the same time notifying the doctor about menstruation. In normal cases it is better to wait for the 8th day of the cycle.

on RW

During menstrual bleeding at study syphilis (RW) the result is not distorted. Rent it is possible, without thinking about choosing the right day. But the doctor may recommend to pass inspection after a 5-8 day cycle.

on hormones

Doctors usually recommend to donate blood on certain days for monthly surveys on sex hormones:

• prolactin;
• testosterone;
• luteinizing (LH);
• Follicle stimulating hormone (FSH);
• cortisol;
• estradiol.

Changes in hormones in the body are significant during menstruation. It is for their content, many doctors put diagnoses related to women's health and reproductive (polycystic, benign tumors, infertility).

hormone levels before menstruation constantly fluctuating, but if significant deviations, they point to the pathology in women. The optimal time for their determination - 2-5 th day of menstruation, but some surveys attached to concrete the phases of the menstrual cycle.

Impact on the hormonal analysis of blood taking pain medications, on the eve of the research on them should be avoided.

Other blood tests

giving blood during menstruation is undesirable or unacceptable for the following studies:

• biochemical analysis. Identify system diseases, which is measured by the content of various enzymes, bilirubin, proteins that menstruating vary slightly (but not recommended to pass the blood);
• determination of tumor markers (in the menstruation period analysis result for the presence of cancer is false positives due to viscosity changes);
• Sugar investigation (determines the level of glucose for diagnosis of diabetes);
• serological analysis for the presence of viruses or bacteria;
• PCR (analysis on the polymer chain reaction requires high precision);
• Allergic sample;
• clotting;
• immunoassay.

Because of the nature of the women's blood changed almost all the important parameters - to a greater or lesser extent.

Possible deviations from the norm

Blood during menstruation becomes enhanced coagulation and viscosity, which contributes to the prevention of large blood loss. When the fence from a vein is a risk that it will be curtailed before the start of the studyIn the end the result will be either false or have to re-take.

In the analysis of blood during menstruation distorted figures:

• D-dimer level (determines the risk of blood clots) is strongly overestimated;
• the detection of some STIs high viscosity lead to false-positive results (even on the identification of many periods will not affect the genital infections);
• settling sedimentation rate in women during menstruation, as well as before menstruation occurs faster than normal, so the identification of inflammations or infections in this manner does not give reliable results;
• significantly reduced hemoglobin, and the number of platelets and leukocytes;
• It increases the number of red blood cells.

Analysis of indicators are considered normal within the following limits:

• leukocytes - 3.5-10 thousands / ml.
• erythrocytes - in the range of 3,8-5,8 million / ml;
• the level of hemoglobin in the blood - 120-160;
• color - 0.8-1.05;
• hematocrit increased in proportion to erythrocytes rate - in the range of 35-45%;
• ESR is normal for women - 3-15mm / h (rising ESR can not only during menstruation, so the examination is always assigned together with more informative).

If you have to undergo an examination, the need to focus on these averages.

Why is not desirable to pass a urine test

Can I take the feces and urine during menstruation? In the first case study allowed only for PKF and worms. A urine analysis on how to take unacceptable during menstruation, and in the next 3-4 days afterwards.

Anatomically, the two systems (reproductive and urinary) are separate, but their outputs are arranged side by side. Vaginal discharge in the microscopic doses necessarily fall directly into the urine in the collection analysis.

Even on ordinary days cycle needed careful hygiene procedures just before the fence urine.

The secretions during menstruation bacteria begin to multiply rapidly. A blood itself contains components, which should not be in the urine of healthy individuals. If the doctor is not going to warn about menstruation, he suspects a bacterial infection or other disease.

Is it possible to be a donor

For donors, there are many restrictions for health reasons. Among them is the menstrual period. Girls can not donate blood during menstruation due to a significant impairment of the body.

Blood has a slight deviation from the norm on the composition, but not suitable for transfusion. women often ignore the ban and become donors during menstruation. There are good reasons why you should not do:

1. Blood sampling occurs in a sufficiently large volume (200 ml for the first time 450 and the next). Plus natural selection during menstruation up to 60 ml per day.
2. During regulation substantially reduced hemoglobin. The greater the loss of blood, the lower the level of a woman feeling worse.
3. It decreases the level of sex hormones, which in itself causes weakness, drowsiness. A further blood loss may bring to the loss of consciousness.
4. Blood pressure changes. Donation greatly exacerbate the situation.
5. During the critical days reduced immunity, the body becomes unstable to diseases. The donation will delay the recovery process.

Only healthy people can be a donor. Not to hurt yourself, it is better not to take blood like during menstruation, and for 3-4 days before and after it:

• before menstruation all indicators as part of the high (hemoglobin, red blood cells), but they are designed to facilitate the state at the time of discharge;
• after a period of critical days for the restoration of the body needs time.

The donor is also desirable to take drugs, and women during menstruation are often forced to use pain medication.
