Yes, a blood test can be used to detect sinusitis. Blood tests can be used to identify whether or not your body is fighting off an infection or if it could be a result of inflammation. Many times when a person is suffering from sinusitis, they will have an elevated white blood cell count, which will be detected in a blood test.
Additionally, if your doctor suspects you may have sinusitis caused by a virus or bacteria, they may order a blood test to determine the presence of antibodies, which will help them accurately diagnose the sinus infection.

What blood tests are done for sinus?
A variety of blood tests can be done to help diagnose sinus issues. These tests typically measure the white blood cell count, total protein and IgE levels (a type of antibody associated with allergies and asthma).
Further tests may be done to determine levels of markers for infection, or to see if specific organs are functioning correctly. Additionally, a blood test may be used to check for signs of auto-immune conditions, or genetics testing may be performed to confirm that the problem is related to sinuses and not another area of the body.
Testing for allergies is an additional blood test option. Finally, blood tests can also look for signs of chronic inflammation such as increased levels of certain cytokines. Ultimately, the type and number of blood tests used for sinus issues will depend on the individual patient’s symptoms and overall health history.
What blood test shows sinus infection?
A blood test is rarely used to diagnose a sinus infection. Typically, the diagnosis of a sinus infection is made based on a physical exam and a review of the patient’s symptoms and medical history. While a blood test may not be able to diagnose a sinus infection, it may be able to detect any underlying medical conditions that could be causing the sinus infection, such as an allergy or other problem.
A complete blood count (CBC) test will examine the amount of red and white blood cells, platelets, hemoglobin and hematocrit, and any visible evidence of inflammation, such as an increase in white blood cells.
An antigen test may detect certain respiratory viruses, including the rhinovirus, which can cause sinus infections. A C-reactive protein test may be offered to detect the presence of inflammation throughout the body, which may suggest an infection.
A comprehensive metabolic panel may be used to detect problems with organ systems that could be contributing to sinus infection symptoms. These tests can help point doctors in the right direction to diagnose and treat sinusitis appropriately.
Will WBC be elevated with sinus infection?
The short answer is maybe. White blood cell (WBC) counts can be elevated as one of the body’s responses to infection, and sinus infections can result in an elevated WBC count. However, this is not always the case, as some sinus infections may not cause a significant elevation in the WBC count.
A few factors can influence whether or not WBC elevations occur in the case of a sinus infection. These include the type of infection, the severity of the infection, and the individual’s own immune system.
In general, bacterial sinus infections, such as those caused by Streptococcus pneumonia, may cause a moderate to large elevation in the WBC count, while infections by other pathogenic organisms may cause a smaller elevation or no elevation at all.
Viral sinus infections may rarely cause elevations, though other virus-induced conditions, such as immune-related illnesses, could potentially cause larger elevations. In addition, the severity of the infection can influence the elevation in WBC counts; more serious infections can lead to larger elevations.
Finally, an individual’s own immune system, which can vary due to wide range of factors, may impact the extent of the WBC elevation. Some individuals may have weaker immune systems or may have difficulty fighting off the infection, and this can lead to higher WBC counts.
Based on these factors, WBC counts can be elevated or not elevated in the case of a sinus infection. The best way to determine the status of one’s WBC count is through a doctor’s appointment and tests.
How do you test for sinus inflammation?
When testing for sinus inflammation, a combination of physical examination, imaging tests, and laboratory tests can be used. During a physical exam, the doctor may look at the nose, ears, and throat and feel along various facial points to locate areas of tenderness and swelling.
Imaging tests, such as a CT scan or MRI, can provide detailed images of the sinuses and nasal passages which can help diagnose inflammation or any other underlying conditions. Finally, laboratory tests, such as a nasal swab or mucus culture, can be used to identify any disease-causing organisms that can be causing the inflammation.
Once these tests are completed, the doctor will determine the best course of action to treat the symptoms, reduce inflammation, and prevent future episodes.
Can sinusitis cause low WBC count?
Yes, sinusitis can cause a low white blood cell (WBC) count. A low WBC count means that there are not enough white blood cells in the body to fight infection. Sinusitis is an inflammation of the lining of the sinuses, typically caused by an infection.
When the body is fighting the infection, it uses white blood cells to do so, and the number of white blood cells in the body can drop. When a person has a low WBC counts, it is common for their body to be more prone to infection, which can lead to a worsening of the sinusitis.
Low WBC counts can also be caused by other problems such as medications, autoimmune diseases, nutritional deficiencies, or extreme stress. It is important to talk to your doctor if you have any signs or symptoms of a low WBC count, such as feeling overly tired, being more prone to infections, or having a fever.
Can a sinus infection cause high neutrophils?
Yes, a sinus infection can cause high neutrophils. Neutrophils are a type of white blood cell that is mobilized from the bone marrow when there is an infection, inflammation, or other stressor. When the body is fighting a sinus infection, it causes a reaction from the immune system that results in high neutrophils.
High neutrophils are often referred to as “bands,” and their presence in the blood can be indicative of an infection or inflammation. A sinus infection will stimulate the immune system to increase production of these white blood cells, leading to an increase in the neutrophil levels seen in the blood.
In cases where the infection is severe, neutrophil levels can become very high, leading to symptoms such as an increased fever and more severe nasal congestion. Treatment for a sinus infection typically includes antibiotics and sometimes decongestants, both of which help to reduce the neutrophil levels in the body and help to control the infection.
What infections cause low WBC?
These infections can be viral, bacterial, fungal or parasitic in nature. Examples of infections that can cause low WBC counts include HIV/AIDS, malaria, tuberculosis, severe viral hepatitis, cytomegalovirus, systemic lupus erythematosus, mycoplasma pneumonia, brucellosis, and sepsis.
Additionally, certain medications such as chemotherapy, glucocorticoid, anticonvulsants, and colchicine can reduce WBC counts. Individuals with suppressed immune systems due to HIV or chemotherapy are also at greater risk of developing bacterial infections.
Other conditions, such as hormone deficiencies and thyroid disorders, can cause low WBC counts; however, these cases are not as common.
How do doctors check for sinusitis?
Doctors check for sinusitis in a variety of ways. The most common is through a physical exam. The doctor will use a light, magnifying instrument to look at the lining of the nose and sinuses. Additionally, they may press or tap gently on the face to feel the sinuses below.
This will help them diagnose the pressure or pain associated with sinusitis.
Other methods that doctors may use to diagnose sinusitis include a CT scan, X-ray, or MRI. These images provide a more detailed look at the structure of the sinuses and any areas of congestion or swelling.
In some cases, an allergist may be consulted in order to determine if an allergen is triggering the sinusitis.
If necessary, the doctor can take a sample from the lining of the sinus during the physical exam and send it to the lab for analysis. This will help to determine if there is bacterial, fungal, or viral infection present that is causing the sinusitis.
In general, the doctor will decide the best course of action for treatment based on the results of their exam, scan, and/or sample analysis. Treatment may consist of antibiotics, antihistamines, anti-inflammatories, and/or decongestants.
What are the 4 main symptoms of sinusitis?
The four main symptoms of sinusitis are nasal congestion, facial pain or pressure, thick nasal discharge, and reduced sense of smell. Nasal congestion is one of the earliest and most common symptoms as the inflammation of the nasal passages causes mucus flow to become blocked which leads to pressure and discomfort.
Facial pain or pressure is often accompanied by headache. Thick nasal discharge is observed from the congested nasal passages and it can be either clear or yellow in color. Reduced sense of smell due to congestion and nasal obstruction is also a common symptom and it can also lead to a reduced sense of taste.
Other common signs and symptoms of sinusitis include fatigue, cough, bad breath, sore throat, and fever.
When should you get checked for sinusitis?
If you’re experiencing any of the symptoms associated with sinusitis, such as a persistent, green or yellow nasal discharge, facial congestion, facial pain and tenderness, difficulty breathing through your nose, or a sore throat that won’t go away, you should get checked for sinusitis as soon as possible.
Additionally, if your symptoms get worse over time or don’t respond to home remedies like nasal irrigation and steam inhalation, you should also seek prompt medical care. Your doctor can conduct a physical exam and diagnostic tests, such as an imaging scan, to determine whether you have sinusitis, and then recommend the best treatment plan for you.
What If sinusitis is left untreated?
Sinusitis is an inflammation of the sinus cavities, usually caused by a virus or bacterial infection. If left untreated, the infection can spread to other parts of the body, including the lungs and brain, and cause serious complications.
Without treatment, a person may experience symptoms such as fever, facial pain, congestion and pressure, coughing, fatigue, and headaches for a prolonged period of time. Furthermore, sinusitis can complicate existing chronic conditions, such as asthma and allergies.
If these conditions are persist, they can lead to more severe and possibly dangerous medical issues. Therefore, it is important to seek medical attention if sinusitis is suspected and to follow treatment instructions provided by a medical professional in order to prevent any worsening of the condition or potential for serious complications.
What is the most common cause for sinusitis?
The most common cause for sinusitis is a viral infection such as the common cold, but it can also be caused by bacterial or fungal infections, allergies, air pollution, nasal polyps, and a deviated septum.
Generally, when sinusitis is caused by a virus, it can last up to 10 days, whereas bacterial sinusitis can last up to four weeks. Allergic sinusitis can last for months or even years, depending on the severity of the allergy.
Air pollution and other irritants can cause chronic sinusitis, which last for several months or longer. Nasal polyps can block the sinuses and cause inflammation, which can lead to sinusitis. A deviated septum, which is a misalignment of the nasal septum, can also lead to sinus congestion and sinusitis.
Treating the underlying cause of sinusitis is the most effective way of treating the condition.
Do you need antibiotics for sinus infection?
It depends. Generally, antibiotics are not necessary to treat a sinus infection, because the vast majority of sinus infections are caused by viruses, which cannot be treated by antibiotics. However, if your sinus infection is caused by a bacterial infection, then antibiotics may be necessary.
To determine if antibiotics are necessary, most likely your doctor will do a physical exam, analyze your symptoms, ask about your medical history, and possibly order a CT scan or other test to determine the cause of your infection.
In some cases, your doctor may recommend a prescription for antibiotics, but usually only if they can confirm that a bacterial infection is the cause of your sinus infection.
