Every person knows the general and biochemical blood tests, so when a doctor sends a patient for their delivery, there are absolutely no questions. But having taken a referral from a doctor for a specific study, many are wondering: blood for MOR, what kind of analysis is this.
Analysis for MOR, transcript
Only if there is a suspicion of such a dangerous disease as syphilis, the doctor prescribes a complete examination of the patient and sends him to the laboratory to donate blood for MOP.
In the language of physicians, the abbreviation MOP refers to the reaction of the immune system in the form of a microprecipitate as a response to the interaction of a soluble cardiolipin antigen with antibodies that are produced by the human immune system. In other words, blood for MOR is a medical screening for the detection of antibodies to the pathogenic bacterium Treponema pallidum in the patient's blood.
Deciphering the analysis is accepted by all laboratories and is indicated by the signs "+". For example, "+" is a weakly positive result, possibly inaccurate or false,needs to be resubmitted. Two pluses "++" - the result is doubtful, three pluses "+++" - one hundred percent positive reaction, four pluses "++++" - an advanced disease, a sharply positive reaction.
How many days does syphilis show up?
Blood tests for sexually transmitted diseases, including syphilis, have been done for a very long time. The founder was the scientist Wasserman. In total, there are 17 reactions to syphilis bacteria, one of them is named after the scientist by the Wassermann reaction.
The reaction manifests itself 10-14 days after infection or household contact with the patient. During this period, it makes no sense to conduct a blood test for MOR, it is better to carry out drug prophylaxis of the disease.
During everyday contact with infected syphilis, a he althy person is infected with pale treponema, due to which he althy cells begin to die in his body. In response to their destruction, the immune system instantly reacts and begins to produce antibodies - special proteins, which in medical terminology are referred to as immunoglobulins. Blood is taken for MOR in order to determine the presence of antibodies to the syphilis bacteria and their concentration (titer).
Ways of contracting syphilis
The causative agent of the disease is pale treponema, it has flagella, with which it can move inside the human body. The main method of infection is direct:
- promiscuity;
- drug needles;
- bites.
To the indirect methodInfection is suitable household contacts through personal items of an infected person. It is especially important in infection with syphilis that pale treponema does not penetrate through intact skin. If there are abrasions, microtraumas on the skin, then infection is inevitable.
Indications for screening
Blood for MOR is given only because of clear suspicion of syphilis, when the patient has signs of the disease. Symptoms of a syphilis infection include:
- subfebrile temperature;
- aches and pains in the bones;
- ulcers and skin lesions on the genitals;
- abnormal vaginal discharge in women;
- rash on body;
- enlarged lymph nodes.
Often this dangerous pathology occurs in a latent form. Given this fact, at the onset of various important events in a person’s life, he will still have to pass a non-specific test for syphilis.
Such life circumstances include:
- employment and passing a medical examination to obtain a he alth book;
- preparation for surgery;
- registration during pregnancy;
- the birth of a child from an infected mother, the baby will urgently be tested for MOR;
- imprisonment;
- sex with an infected person;
- appearance of signs of venereal disease.
Patients undergoing medical therapy periodically donate blood to the MOP to evaluate the effectiveness of the chosen treatment. AfterAfter completing the course of drugs, doctors prescribe a control test for syphilis.
There are categories of citizens who are required to periodically take a general blood test of the MOP to detect infection and prevent the spread of the disease. These include he althcare workers, penitentiary officers, "industrialists" and drug and alcohol addicts.
Responsible blood sampling
Blood for screening is given in the same way as for biochemistry - on an empty stomach. Many patients who have a fear of blood or a high pain threshold are concerned about the question of where they take blood for MOR. From a finger or a vein, depending on the laboratory. If a pathogenic bacterium - pale treponema - is detected, treatment should be started immediately. In 90% of cases, the therapy is effective, and the MOR control test will become negative.
Besides being negative or positive, a test can also show a dubious result. This indicates a neglected course of the disease.
How to get tested. Doctors' recommendations
Patients who are faced with the need to be tested for syphilis for the first time are wondering how to donate blood to MOP. There are several rules that are recommended to be followed before donating blood to get a reliable result.
Like many other tests, blood for MOR is taken on an empty stomach. It is allowed to drink water, but a small amount and without gas. Excluded alcoholic beverages, as well as spicy and fried foods saturated with fats. Diet neededobserve if there is a need to donate blood for a microreaction of precipitation. If a person is taking any medication, then before taking blood, he is obliged to inform his doctor about this. Perhaps he will stop taking drugs for a certain period so that the result of the analysis is not affected by foreign drug impurities in the blood.
False positive result - what is it and how to understand it?
The analysis does not reflect the pathogenic bacterium itself, but only traces of its presence in the human body. The MOR test finds and counts antibodies in a person's blood that are produced in response to an infection.
The result of the analysis in some cases may be false positive and this is due to certain human conditions.
These include:
- pathology of the autoimmune system;
- inflammatory processes in the body;
- pregnant or recent childbirth;
- diseases caused by other infections, viruses;
- disruptions in the endocrine system;
- history of syphilis;
- vaccination;
- alcohol, drug intoxication.
In patients with tuberculosis, HIV, hepatitis, leprosy, a test for syphilis can also show a false positive reaction. Surprisingly, even with menstruation in women, the result of the analysis can scare with two pluses. According to statistics, 5% of the surveyed have a false result. In this case, you need to retake a blood test for MOR.
How long does it take to receiveanalysis result?
Time and speed of execution depends on the laboratory and its capabilities. On average, the result of a blood test for MOR can be obtained after 10 days. The more technically equipped the laboratory, the faster the screening will be performed. This usually takes from several minutes to several hours. If few analyzes for processing are currently provided, the laboratory accumulates material to fully load the analyzer. To find out how much a blood test is done for MOR, you need to find out this question in the laboratory where you plan to donate blood.
The actions of a person with a positive test for syphilis
If a patient sees three or four pluses when receiving the results of a blood test for MOR, which means a positive antibody reaction to pale treponema, then he should have a second or even a third control test for syphilis, preferably in different laboratories. This is done to eliminate errors and obtain a reliable result. It is necessary to find out in advance in these laboratories how much blood is made on the MOR and immediately contact a venereologist to prescribe treatment. To make sure that the analysis is correct, the following mini-test is carried out in the laboratory: a cardiolipid antigen is applied to a drop of blood serum. The final diagnosis and treatment is carried out by a venereologist.
The Ministry of He alth has developed a number of measures to prevent syphilis. For example, to prevent congenital syphilis in babies, pregnant women during observations in the antenatal clinicperiodically hand over a blood on RW. This is also a test for syphilis, expectant mothers must check the blood without fail. If a pathogenic bacterium is detected in a woman during pregnancy, complex treatment will be prescribed. Ignoring treatment with dangerously irreversible consequences for the mother and her unborn baby.
