Blood tests and lymphadenopathy?


Hello Doctor, a few days ago I had a blood test and found that my monocyte count is 11.4, which exceeds the normal range.
I would like to know what issues I might be facing.

Background: This series of blood tests was conducted because I was diagnosed with ankylosing spondylitis and have been taking Celebrex since last summer.
Since September, I have also been taking traditional Chinese medicine for generalized anxiety disorder, but I stopped over two weeks ago.

Additionally, at the beginning of January, I noticed swelling in the lymph nodes on both sides of my groin (I'm not entirely sure, as the traditional Chinese medicine doctor I saw two weeks ago said they felt normal).
On the right side, I can feel a chain of nodes, each about one centimeter or less, some round and smaller, while others are slightly elongated.
The left side has a similar situation but is less pronounced than the right.
Recently, I feel like the right side has shrunk a little (but I'm not certain).

I have been feeling more fatigued lately, possibly due to poor sleep habits.
Other than that, I don't have any significant discomfort.
Below are the results of my recent blood tests (from the most recent to last year):
- Early February: MCV 87.6, RBC 4.75, RDW 13.2, WBC 5.6, creatinine 0.7, estimated GFR (MDRD) 143.8, AST (GOT) 21, CRP 0.19, Ht 41.6, Hemoglobin 13.7, Seg 56.3, Mono 11.4, Lymp 28.9, Eosin 2.7, Baso 0.7, Platelet 357, E.S.R.
1hr 8
- Early October: Platelet 287, Mono 9.2, Baso 0.5, Eosin 2.5, Seg 56.8, Hemoglobin 13.9, Ht 41.2, MCV 87.7, RBC 4.7, RDW 13.8, WBC 4.88
- End of August: HCT 42.4, MCH 28.9, MCHC 32.5, MCV 88.7, PLT 334, RBC 4.78, RDW-CV 12.5, WBC 5.96, Baso 0.5, Eosin 2.9, Lym.
30.7, Mono 6.2, Seg 59.7, HB 13.86
- End of July: Eosin 3.9, HB 14.8, HCT 44.4, MCH 28.8, MCHC 33.3, MCV 86.5, PLT 324, RBC 5.13, RDW-CV 12.2, WBC 6.61, Mono 5.4, Seg 53.9
Thank you for your assistance!

In a complete blood count (CBC), it is sufficient to monitor whether the WBC, HB, and PLT are within the normal range.
Other white blood cell differentials may vary in elevation or decrease depending on physiological conditions.
For example, monocytes may slightly increase during infections (especially viral infections), inflammation, or after the recovery of bone marrow function following the use of certain myelosuppressive medications.

More Info


Understanding elevated monocyte levels and lymph node swelling can be crucial for diagnosing underlying health issues. Based on your provided information, it appears that you have elevated monocyte levels (11.4), which exceed the normal range, and you are experiencing lymph node swelling in the groin area. Let’s break down what these findings might indicate and how they relate to your overall health.


Elevated Monocyte Levels
Monocytes are a type of white blood cell that plays a vital role in the immune system. They help fight infections and respond to inflammation. Normal monocyte levels typically range from about 2% to 8% of the total white blood cell count. An elevated level, such as your 11.4, can indicate several conditions, including:
1. Infection: Monocytes often increase in response to infections, particularly viral infections. Given that you have a history of ankylosing spondylitis and have been on medication, it’s possible that your immune response is heightened due to an underlying infection.

2. Inflammation: Chronic inflammatory conditions, such as ankylosing spondylitis, can lead to elevated monocyte levels. The inflammation associated with your condition may be contributing to this increase.

3. Autoimmune Disorders: Conditions like rheumatoid arthritis or lupus can also result in elevated monocyte counts as the body’s immune system is activated.

4. Stress Response: Physical or emotional stress can lead to changes in blood cell counts, including monocytes.


Lymph Node Swelling
The swelling of lymph nodes, particularly in the groin area, can be due to various reasons:
1. Infection: Lymph nodes often swell in response to infections, as they filter out pathogens. The fact that you have noticed swelling in both sides of your groin could indicate a localized infection or a systemic response to a viral infection.

2. Inflammatory Response: Similar to elevated monocytes, lymph node swelling can occur due to inflammation in the body, which could be related to your ankylosing spondylitis.

3. Malignancy: Although less likely given your symptoms and the nature of your lymph nodes, persistent swelling can sometimes indicate a more serious condition, such as lymphoma or other cancers. However, the absence of other alarming symptoms (like significant weight loss, fever, or night sweats) makes this less likely.


Recommendations
1. Follow-Up with Your Doctor: Given your elevated monocyte levels and lymph node swelling, it is essential to follow up with your healthcare provider. They may recommend further testing, such as imaging studies (like an ultrasound of the lymph nodes) or additional blood tests, to determine the cause of these findings.

2. Monitor Symptoms: Keep track of any changes in your symptoms, such as increased fatigue, fever, or changes in the size of the lymph nodes. This information can be helpful for your doctor.

3. Consider Lifestyle Factors: Since you mentioned feeling more fatigued and having irregular sleep patterns, addressing these lifestyle factors can also help improve your overall health and immune function.

4. Medication Review: Discuss with your doctor the medications you are currently taking, including the use of Celebrex (celecoxib) and any herbal remedies. Some medications can influence blood counts and immune responses.


Conclusion
Elevated monocyte levels and lymph node swelling can be indicative of various conditions, ranging from infections to chronic inflammatory diseases. Given your medical history and current symptoms, it is crucial to maintain open communication with your healthcare provider to ensure appropriate evaluation and management. Regular monitoring and follow-up can help address any potential health concerns early on.
