If you're searching “blood tests normal but still feel unwell,” normal results mean the tests performed did not identify certain abnormalities—not that your symptoms are imaginary. Persistent exhaustion, aching, or brain fog deserves a medical review that considers your history, examination, sleep, medications, and carefully selected next steps. MaxGen DRP genetics may add context about selected inherited variants, with CMA + Redox considered afterward when a cellular nutrition question remains; neither replaces medical care or guarantees an explanation.
I want clients to hear two things together: reassuring results matter, and how you feel matters. You do not have to reject one to take the other seriously.
At Purser Wellness, my featured genetic option is the MaxGen DRP panel. It starts a discussion about possible contributors—not a verdict about why you feel sick.
Step 1: Understand what “normal” actually answers
A routine panel answers a defined set of questions. It does not examine every possible reason for fatigue, pain, or difficulty concentrating.
A reference range generally comes from results in a group considered healthy. Your clinician interprets it alongside your age, symptoms, examination, and other findings. As MedlinePlus explains, results inside the range do not guarantee good health, and results outside it do not automatically mean disease.
Ask which tests were performed and what remains uncertain. Trends can matter, although laboratory methods and units can complicate comparisons.
Routine tests are valuable. Clarify what they tell us rather than dismissing them or assuming a hidden deficiency.
Step 2: Describe the symptoms before choosing more tests
“Normal blood work but still feel sick” is a starting point, not a diagnosis. Tell your clinician what feeling sick means in daily life.
Is it sleepiness, muscle weakness, widespread aching, breathlessness, or an energy crash after activity? Did it begin after an infection, a new medication, a change in sleep, or a major life event?
Keep a brief diary of symptom timing, sleep quality, meals, activity, and the tasks you can no longer manage comfortably. Bring previous reports and a complete medication and supplement list.
Clients sometimes describe feeling “inflamed.” I take that discomfort seriously, but the sensation alone does not establish inflammatory disease. Stiffness, joint swelling, fever, rashes, or other specific findings help guide the assessment.
Step 3: Revisit common causes—and recognize urgent symptoms
Before exploring specialized nutrition testing, review conditions such as anemia, thyroid disease, sleep apnea, medication effects, depression, anxiety, and recovery after infection. What has already been evaluated, and what does your history suggest still needs attention?
Temple Health's explanation makes an important distinction: iron deficiency can exist without anemia, and sleep apnea cannot be diagnosed by a routine blood panel. Sometimes the useful next step is a sleep assessment or medication review, not another broad panel.
Do not stop prescribed medication on your own. If activity causes a delayed, substantial worsening, describe that pattern rather than trying to push through it.
Seek emergency care for chest pain, severe shortness of breath, fainting, sudden weakness, or trouble speaking. Unexplained weight loss, persistent fever, or worsening symptoms also warrant prompt medical attention. A previous normal report does not cancel a new warning sign.
Step 4: Explore the MaxGen DRP panel—with clear limits
I designed the DRP panel drawing on four years of work with clients. My aim was to explore genetic contributors to inflammation-related questions, including homocysteine-related pathways and selected inflammation-related gene targets: IL6 (IL-6), CXCL8 (IL-8), IL23R (interleukin-23 receptor), and TNF (TNF-alpha). IL23R is a receptor gene; these are not all cytokine genes. That is the clinical background behind my design, not a validation study proving the panel explains unexplained symptoms.
The MaxGen DRP bundle is the centerpiece of that conversation. Genetic counseling and results discussion with me can be arranged via Zoom, subject to availability and service requirements. This means physician interpretation; a separately credentialed genetic counselor is not promised.
I also have a clinical interest in PEMT when discussing gut concerns, including SIBO, and liver, gallbladder, or pancreas questions. Those are questions to explore, not conditions a PEMT variant diagnoses. A result does not establish that a variant caused symptoms or replace appropriate evaluation of those organs.
The distinction matters: DRP examines selected inherited variants. It does not measure cytokine concentrations, homocysteine concentrations, current nutrient levels, or active inflammation. A variant is not a diagnosis, and a reassuring panel cannot rule out illness.
MedlinePlus Genetics explains that genetic testing has important limits and potential emotional and financial consequences. Ask which findings would change care and discuss privacy before ordering. Genetic testing is never a prerequisite for appropriate medical care.
For a separate discussion of how to lower homocysteine , see my dedicated guide. This article is not a treatment protocol, and unexplained fatigue should not automatically be attributed to methylation.
Step 5: Consider CMA + Redox only if a nutrition question remains
Genetics and cellular assessment answer different questions. After reviewing your history and, if chosen, your DRP results, we may consider the Cellular Micronutrient Assay with Redox. It is an optional follow-up, not a required second purchase. Some clients may need a different evaluation or no additional testing.
CMA examines aspects of nutrient function within immune cells; Redox adds antioxidant-related assessment. It may inform a nutrition discussion, but it does not directly measure every organ or every cell. A flagged finding does not prove the cause of pain or exhaustion, or confirm that a genetic variant is causing a deficiency.
Evidence that broad intracellular panels improve clinical outcomes beyond standard assessment remains limited. An evidence review used for coverage decisions finds insufficient evidence of better long-term outcomes. Ask what the result could change, whether confirmation is needed, and whether the expense is justified for your question.
Step 6: Compare the purpose, inclusions, and expense
Here is one practical comparison. Prices below were checked against the Purser Wellness pricing page on November 8, 2026, HST; confirm them before ordering.
| Assessment | What it can contribute | Important limit and listed cost |
|---|---|---|
| Medical review with targeted evaluation | History, examination, and assessment for likely causes | No single panel rules out everything; cost depends on the care selected |
| DRP genetics through MaxGen with Dr. Purser consultation | Selected inherited variants and interpretation | Not current nutrient status or a diagnosis; $925 |
| Optional CMA with Redox and staff consultation | Cellular nutrient-function and antioxidant-related assessment | Not proof of symptom cause; $799; CMA without Redox $599 |
| Optional CMA with Redox and Dr. Purser consultation | Cellular assessment with physician interpretation | Not a guaranteed answer; $1,224; CMA without Redox $1,024 |
The CMA physician bundle lists a 30-minute consultation and customized supplement and nutrition plan. You arrange the blood draw with a qualified provider; outside draw fees vary. The DRP physician bundle lists a 30-minute consultation.
These Purser Wellness offerings are direct-pay and never billed to insurance. Reimbursement is not promised. Confirm total charges, follow-up, separate draw fees, and the appointment format before ordering. Written-consult offers differ from live consultations; a nutrition plan does not mean supplements are included.
Step 7: Leave with a plan and a review point
A useful consultation should end with priorities, not just more information. What needs medical follow-up? What reasonable nutrition or sleep changes can begin? Which findings remain uncertain, and when will you review progress?
Choose recognizable outcomes: managing a workday or sleeping more restoratively. Do not chase every flagged result or assume supplements will resolve the problem. Discuss safety, interactions, and whether further testing would change care.
The Purser Method describes our approach to individualized assessment. If aching is your main concern, our pain-management overview provides additional practice context; it does not replace an examination or establish your personal diagnosis.
Before-your-visit checklist
Bring actual reports, not just “everything was normal.”
Write down symptoms, onset, triggers, and daily impact.
List prescriptions, nonprescription products, and supplements.
Note snoring, unrefreshing sleep, and activity-related worsening.
Ask what each proposed test could change.
Confirm who interprets results and all separate fees.
Agree on follow-up and warning signs requiring earlier care.
If you're always tired but blood tests normal, the next step is a better clinical question—not automatically a bigger shopping cart. For questions about Purser Wellness options, email info@danpursermd.com.

Frequently asked questions
Can I feel unwell even when blood tests are normal?
Yes. Routine tests assess specific things, not every possible cause of symptoms. Persistent fatigue, pain, or brain fog deserves review of your history, examination, sleep, medications, and whether targeted evaluation is appropriate.
Does normal blood work rule out inflammation?
No. The meaning depends on which tests were performed and your clinical findings. Aching or feeling inflamed does not itself establish inflammatory disease. Discuss persistent symptoms, swelling, fever, or other changes with your doctor.
Do I need CMA + Redox after DRP genetics?
No. CMA + Redox is an optional follow-up when a cellular nutrition question remains. It does not confirm that a genetic variant is causing symptoms. Evidence for improved outcomes from broad intracellular panels remains limited; other medical evaluation may be more useful.
Can a genetic test diagnose why I feel sick?
No. A selected variant is not a diagnosis and does not measure current nutrient levels. Genetic results need interpretation alongside your symptoms and other findings; many variants do not explain illness.
Are Zoom consultations and insurance billing available?
Genetic counseling and results discussion with Dr. Purser can be arranged via Zoom, subject to service requirements and availability. These Purser Wellness offerings are direct-pay and never billed to insurance. Confirm inclusions and separate fees; reimbursement is not promised.
