It’s critical to keep an eye on a number of health indicators during pregnancy to make sure the mother and unborn child are doing well. The "Relative Fetal Movement Count," or RFMC, is one example of such a measurement. This indicator aids medical professionals in determining the infant’s general health and activity level. Gaining knowledge about why RFMC is monitored and what it indicates when it is elevated can be extremely beneficial for prenatal care.
Occasionally, an elevated RFMC may indicate possible problems that require attention. Understanding the meaning of this indicator is crucial because it facilitates decision-making regarding additional diagnostic testing or modifications to care protocols. Keeping an eye on these movements makes it possible to identify possible issues early on, which is important for properly managing the health of both the mother and the child.
It is crucial for expectant parents to understand how to react in case of an elevated RFMC. To identify the cause and make sure that all required actions are taken to address the situation, this may entail further medical evaluations. Maintaining awareness and taking initiative can help you have a more positive pregnancy experience.

What is it?
The name "RFMC" for a laboratory marker is not complete. Although it is referred to by doctors as soluble fibrin monomer complex, it is actually much simpler to use the acronym RFMC. This material is unique in that fibrinogen binds to its precursors for homeostasis because of its chemical makeup. The bloodstream is actively filled with RFMC molecules. Hemostasis indicators can be found through specialized testing. The body needs fibrinogen and the products of its metabolism. The formation of a blood clot is the last stage of the homeostasis reaction. This kind of response is physiologically required.
A human body could perish from any kind of bleeding, no matter how small, if blood fibrin clots did not form in it.
Fibrin clot formation is a gradual process. Initially, it separates into two monomers, A and B, from the original fibrinogen molecule. Thrombin aids in the development of this reaction. The next step is to combine these monomers with ionized calcium molecules. The blood clot starts to assemble physically at this point. Fibrinoligase is a unique enzyme that causes the texture to change to a denser one. Another name for it is coagulation factor XIII. The body needs this intricate series of biological processes in order to be physiologically shielded from any bleeding or blood loss.
Physicians view RFMC as a crucial clinical indicator of how the intravascular coagulation process is progressing. By analyzing this signal, experts can spot new diseases at the very beginning of their development.
Norms
Experts have determined what the normal blood levels of this substance should be. The range of the average norm is 3.3–4 mg/100 ml. Pregnancy may cause changes in this laboratory marker’s values. By the third trimester, these changes become most noticeable. In this instance, the majority of women’s blood levels of RFMC are rather high. A future mother will almost never be prescribed to take just one hemostasis indicator by a doctor. Usually, a number of combined clinical markers must be determined in order to identify the pathology.
As a result, in order to measure D-dimer, APTT, and other hemostasis markers, the future mother must also give blood.
Researchers have found that the first changes in blood clotting in pregnant women begin to occur as early as 13-15 days from the moment of conception, that is, after the attachment (implantation) of the baby to the wall of the uterus. If this process is completed successfully, then this is evidence that the child"s fetal blood vessels are becoming active. Doctors also call this new blood flow system fetal. The active work of the baby"s blood vessels provokes changes in the hemostasis of his mother. As the fetus grows and develops intrauterinely, the RFMC levels in the mother"s blood will also change. Usually this happens gradually and by weeks of pregnancy. The growing fetus contributes to the fact that the mother"s body begins to experience a gradual increase in the RFMC concentration. A statistically significant increase in the indicator occurs by the second trimester of pregnancy. In the first weeks from the moment of conception, the RFMC concentration does not change significantly.
Moreover, the blood’s RFMC level is only getting higher.
It is significant to note that pregnant women’s blood levels of this indicator vary depending on the stage of their pregnancy. Special tables are used by doctors. They show the typical values of the investigated laboratory parameters. Below is one of these tables:
Pregnancy period | Normal RFMC concentration (mg / 100 ml) |
1 trimester | 5.5 |
2 trimester | 6.6 |
3rd trimester | 7.5 |
Upon close examination of the table, we can observe that this indicator rises noticeably by the time a woman reaches the end of her reproductive cycle. Such a change was not created by nature by happenstance. Thus, the expectant mother’s body is getting ready for the impending significant blood loss.
It is significant to remember that other clinical markers of hemostasis also alter in addition to the RFMC concentration.
Maternal risk factors, or RFMC, are evaluated during pregnancy to make sure the mother and unborn child are healthy. An elevated RFMC level may be a sign of possible problems that need to be closely monitored, such as preeclampsia or gestational diabetes. Preventing complications and ensuring a safer pregnancy are ensured by early identification and management of these risk factors. In order to protect your health and the health of your unborn child, it’s critical to heed your healthcare provider’s advice if your RFMC levels are elevated. This advice may include lifestyle modifications, closer observation, or targeted treatments.
Reasons for the increase
It’s possible that the rise in RFMC isn’t just physiological. Disorders develop in this scenario far more quickly than they do by the third trimester of pregnancy. These deviations can happen by the 26th or 28th week of pregnancy, or even earlier, for a lot of expectant moms. These conditions already point to issues with the female body. In a situation like this, it’s important to figure out what caused the changes to occur.
Blood RFMC values that are positive don’t indicate the presence of any pathology. This material is typically always determined. Physicians assess the concentration of RFMC in the blood rather than its existence.
It will be necessary to conduct additional diagnostic tests to determine the reason behind these changes if the expectant mother’s blood concentration of this substance is noticeably elevated. The blood’s concentration of RFMC rises in thrombosis. Pregnant women typically have a much higher chance of developing this pathology. The propensity for thrombosis exists even in the absence of pregnancy. Heredity has an impact on the pathology’s development. Blood viscosity and fluidity changes are associated with disseminated vascular coagulation syndrome, or DIC syndrome. RFMC is one of the evolving laboratory requirements.
This indicator’s blood concentration increases with the severity of the pathology.
Hemostasis is also compromised in women experiencing gestosis or severe toxicosis. There is an elevated risk for expectant mothers who are carrying twins or triplets. Additionally, women who have had in vitro fertilization should take the test more frequently. In this situation, closer observation of the RFMC level and other hemostasis indicators is required. This indicator may rise if the expectant mother is compelled to take hormone medications while she is pregnant.
Such disorders are also more likely to develop in pregnant women who continue to smoke or consume alcohol.
For expectant mothers with various rheumatological diseases and cardiovascular pathologies, doctors advise monitoring RFMC levels in the blood. A woman who suffers from arrhythmia or irregular heartbeats faces a risk of dangerous thrombosis if her blood RFMC level rises. This substance’s blood levels can rise even in cases of common infectious diseases. In this instance, there is a slight increase in the blood’s RFMC concentration. Hemostasis indicators return to normal once the overall condition has stabilized. Endocrine system disorders may also result in elevated RFMC. The most prevalent conditions that lead to the development of these disorders are diabetes mellitus and thyroid pathologies.
How is a blood test performed?
The methodology for this laboratory test is very simple. For this, venous blood is taken. The expectant mother can undergo such a study both in a clinic and in a private laboratory. It is better to take this test on the recommendation of a doctor. If a woman has any hemostasis pathologies, then a therapist or hemostasis specialist will refer the expectant mother for testing. The test should be taken strictly on an empty stomach. To obtain more accurate results, it is necessary to limit the consumption of fatty and fried foods the day before going to the laboratory. Before donating blood, you can only drink a little water. No special preparation is required before going to the laboratory. Doctors only recommend eliminating the use of anticoagulants before the study. This should be done 1-2 days before going to the laboratory.
You should definitely speak with your doctor before stopping these medications.
Consequences for the child
Numerous blood clots form in the general blood flow system between the mother and the fetus as a result of an increase in RFMC in the blood. Their clogging of the artery lumen causes the baby’s supply of different nutrients to be reduced. The infant’s intrauterine development is negatively impacted by this circumstance. Persistent fetal hypoxia is partly caused by occlusion of the uteroplacental blood vessels. This can result in a variety of intrauterine developmental anomalies and defects if the situation persists long enough.
Why RFMC is Determined | RFMC (Relative Fetal Movement Count) is monitored during pregnancy to assess the baby"s health and activity level. It helps ensure the fetus is developing normally and responds to various conditions in the womb. |
Importance of Monitoring RFMC | Monitoring RFMC can help detect potential issues early. If the baby"s movement decreases or changes significantly, it may signal problems that require medical attention. |
What to Do with Increased RFMC | Increased RFMC can be normal, especially in the later stages of pregnancy. However, it can also indicate potential issues like fetal distress. It"s important to consult a healthcare provider if there are sudden changes or concerns about the baby"s activity. |
Relative fetal heart rate variability, or RFMC, is a crucial metric measured during pregnancy to guarantee the health of the unborn child. It assists medical professionals in keeping an eye on the infant’s heart rate patterns and identifying any possible problems early on. Knowing the rationale behind RFMC measurement can reassure expectant parents and increase their sense of knowledge regarding the health of their unborn child.
An elevated RFMC typically indicates a higher degree of variability in the baby’s heart rate. While this may occasionally point to a problem, more research is frequently necessary to identify the root cause. Usually, more examinations and evaluations are carried out by medical experts to determine the possible causes of the elevated variability.
Expectant parents should remain composed and adhere to the advice of their healthcare provider. It may be necessary to conduct additional testing or monitoring to make sure everything is going according to plan. For any concerns to be addressed and to guarantee that mother and child receive the best care possible, open communication with healthcare professionals is essential.
