What level of D-dimer is dangerous? Truly D-dimer is the amount of substance in the blood that is very essential to help identify other health complications most of which are associated with coagulation problems.
But what D-dimer level is lethal? It is crucial to know the potential health risks that might exist and therefore control them.
The purpose of this article is to examine what D-dimer entails, what constitutes normal and high levels, causes as well as symptoms of raised levels of D-dimer, and methods of remedying the condition.
What is D-Dimer Test?
A D-dimer test is a blood test used to detect the presence of D-dimer, a protein fragment produced when a blood clot dissolves in the body.
This test is often used to rule out or diagnose conditions related to excessive clotting, such as deep vein thrombosis (DVT), pulmonary embolism (PE), and other clotting disorders.
However, understanding what level of D-dimer is dangerous is key to interpreting the results correctly.
D-Dimer Normal Range by Age
The factor that points towards the utility of D-dimer levels as a biomarker is that they may differ depending on the age of a patient.
It is generally expected that normal adult patients will have a D-dimer of less than 500 ng/mL (nanograms per milliliter). However, using the baseline of D-dimer levels, the increase in which people as they age must be considered.
This gives rise to another important question; at what level does D-dimer become hazardous when a person is older?
An often employed approximation for establishing a normal D-dimer level in elderly patients is to multiply their age (in years) by 10 ng/mL.
It is quite possible that in a 70-year-old patient, the D-dimer level can be even as high as 700 ng/mL and deemed normal.
What Is a High D-Dimer Level?
An elevated D-dimer level is commonly discussed to be a level that is above normal reference for the person’s age group.
In general, for all adults under fifty the measurement above 500 ng/mL is regarded as elevated.
But what level of D-dimer is dangerous? In other words, when D-dimer levels are high, this may point at an existing problem but does not in any way identify what the problem is.
To this end, it recommends that more tests and assessments should be done to get to the root of the problem.
High D-Dimer Causes
Several conditions can lead to elevated D-dimer levels, most of which are related to abnormal blood clotting.
Knowing what level of D-dimer is dangerous can help identify these conditions early. Some of the most common causes include:
Deep Vein Thrombosis (DVT)
Blood clots develop in the deep veins most commonly in the lower limbs and are characterized by inflammation, scraping, and pain.
Pulmonary Embolism (PE)
The blood clot dissolves and moves to the lungs where it lead to abrupt shortness of breath and chestache. Indeed, knowing what level of D-dimer is unsafe may sometimes determine whether a patient is going to survive this condition or not.
Disseminated Intravascular Coagulation (DIC)
A serious disease characterized by the over-activation of the blood coagulation proteins and the resultant clot formation in the body.
It is possible to learn What level of D-dimer is dangerous and thus guide the treatment to be taken.
Recent Surgery or Trauma
Some surgeries surgical procedures and high incidences of physical trauma also tend to raise D-dimer levels by bouts of coagulation activity.
Pregnancy
D-dimer is increased during pregnancy unless accompanied by symptoms; in that case, it is usually not a concern. However, it is necessary to know What level of D-dimer is dangerous during pregnancy.
Infections
Suspected infections can activate the clotting process of the body and hence increase the levels of D-dimer.
Cancer
They include pancreatic, lung, and stomach cancer among others can lead to raised D-dimer levels.
To this end, it pays to know what level of D-dimer is dangerous to assist in early diagnosis and management.
High D-Dimer Symptoms
High D-dimer levels themselves do not produce symptoms, but the underlying conditions associated with elevated D-dimer levels do. So, what level of D-dimer is dangerous, and what symptoms should you watch for?
Symptoms to watch for include:
- Deep Vein Thrombosis (DVT): Swelling, pain, warmth, and redness in the affected leg.
- Pulmonary Embolism (PE): Sudden shortness of breath, chest pain, rapid heart rate, and coughing (possibly with blood).
- Disseminated Intravascular Coagulation (DIC): Uncontrolled bleeding, bruising, low blood pressure, and organ failure.
These symptoms can be severe and potentially life-threatening, requiring immediate medical attention, especially if you’re unsure what level of D-dimer is dangerous.
How to Treat High D-Dimer Levels
Management of high D-dimer levels depends on what level of D-dimer is dangerous and the cause.
Some potential treatment options include:
- Anticoagulant Medications: Heparin and warfarin are some of the most known anticoagulation medicines that are used in cases such as DVT and PE.
- Thrombolytic Therapy: This consists of dissolving the existing clots through the administration of a group of medicines that is popular, especially in cases such as a pulmonary embolism.
- Surgery: At times, it might be necessary to have surgery to have the clot removed especially when the DVT or PE has reached serious levels.
Knowing what level of D-dimer is dangerous can define whether surgery is necessary.
- Addressing Underlying Conditions: Patients’ D-dimer levels could be decreased if the basic cause including infections or cancer is addressed.
High D-Dimer but No Clot
It’s possible to have elevated D-dimer levels even in the absence of an active clot. What level of D-dimer is dangerous in these situations?
This can occur in cases like:
- Pregnancy: Plasma D-dimer concentrations are conditioned to increase during pregnancy because of a hypercoagulable state, but elevated D-dimer does not mean a thing.
- Recent Surgery: D-dimer is clarified to rise as a result of surgery because the body is still healing.
Understanding what is a dangerous D-dimer level after surgery helps to monitor it adequately.
- Chronic Conditions: There are chronic diseases which if the patient has are likely to have high D-dimer levels for example liver diseases or inflammatory conditions.
What Infections Cause Elevated D-Dimer?
Infections are another cause of inflammation in the body, and this causes the D-dimer levels to be raised.
It is important to know What level of D-dimer is dangerous for infections.
Some of the infections known to cause this include:
- Sepsis: A dangerous systemic inflammatory response to an infection that may cause coagulation in all tissues and increased D-dimer.
It is consequently important to be certain of what range of D-dimer is risky for sepsis so that intervention is possible in good time.
- Pneumonia: The lung infections particularly severe ones escalate clotting activity in the body thereby raising D-dimer levels.
Knowing What level of D-dimer is dangerous during pneumonia can help in management.
- COVID-19: It is a viral infection with reported hypercoagulopathy and raised D-dimer predominately when the condition is severe.
Since understanding which level of D-dimer is hazardous in COVID-19 may be crucial, the study aimed to compare the D-dimer levels combined with other indicators in subjects infected with SARS-CoV-2 and healthy individuals.
