Key Takeaways
- A flagged number alone does not establish a diagnosis.
- Check the reference range on your own laboratory report.
- Ask your clinician how quickly you need follow-up.
- Share symptoms, medications, supplements, and preparation details.
- Confirm whether you need repeat testing or another evaluation.
- Seek emergency help for serious symptoms instead of waiting for an appointment.
If you receive abnormal blood test results, contact the clinician who ordered your tests and ask what follow-up you need. A high or low flag does not automatically confirm a disease. Your clinician considers your symptoms, medical history, examination, and other findings before recommending next steps. Meanwhile, follow any urgent instructions from your care team.

Seeing a red mark in your patient portal can feel unsettling. However, you do not have to interpret every number alone.
What Does an Abnormal Blood Test Result Mean?
An abnormal result often means your measurement falls outside the laboratory’s reference range. Your report may show an “H” for high, an “L” for low, or another attention flag.
However, reference ranges can differ between laboratories. Therefore, compare your number with the range beside it rather than a number from an unrelated website.
Also, healthy people sometimes have results outside these ranges. Conversely, a result within range does not always rule out a health problem. Your clinician needs the broader picture to explain your abnormal blood test results.
Does a Slightly Abnormal Result Always Mean Something Serious?
No. Nevertheless, a small difference does not automatically mean you can ignore it. Ask your clinician whether the change matters for that particular test and your health history.
What Should I Do First After Receiving Abnormal Blood Test Results?
Start with a practical plan:
Read the accompanying message. Look for instructions from the ordering clinician.
Identify the exact test. Note its name, value, units, and reference range.
Contact the ordering office. Ask when you should discuss the findings.
Prepare your questions. Write down anything you do not understand.
Confirm responsibility. Ask who will arrange additional tests and communicate results.
For example, you might ask: “My report shows a high result. Do I need an appointment, another test, or instructions today?”
This question helps the office understand what you need without requiring you to diagnose yourself.
What If My Portal Shows Results Before My Doctor Calls?
You may see findings before your clinician explains them. The National Cancer Institute acknowledges that this timing can cause anxiety and recommends discussing results with your doctor. [NCI]
Meanwhile, use the portal or telephone to request clarification. Ask when to expect a response and what to do if you develop symptoms.
When Do Abnormal Blood Test Results Need Urgent Attention?
Follow immediate instructions from your clinician or laboratory. If someone tells you a result requires urgent assessment, act on that advice even if you feel well.
Separately, serious symptoms require emergency care regardless of what your report shows.
Important warning: Call 911 for chest pain that suggests an emergency, severe breathing difficulty, new confusion, loss of consciousness, or sudden difficulty speaking. Do not wait for a routine blood test follow-up or a portal reply.
If the report says “critical” and you have no instructions, contact the ordering clinician immediately. If you cannot reach the office, seek urgent medical guidance.
What Information Helps My Doctor Explain the Results?
Before your appointment, gather information that could help your clinician interpret your findings.
First, list your medications and supplements. Include prescription treatments, nonprescription medicines, vitamins, and herbal products.
Next, explain your preparation. Mention whether you followed fasting instructions or took medication before the blood draw. Some tests require specific preparation, while others do not.
Also, describe recent symptoms or health changes. Bring a short timeline rather than trying to remember everything during the visit.
Finally, do not stop medication or start supplements simply to change a laboratory number. Ask your clinician for instructions first.
Which Blood Tests Commonly Raise Questions?
Different tests answer different questions. Therefore, ask what each measurement contributes to your evaluation.
A CBC includes several measurements rather than one overall score. For example, it measures red blood cells, white blood cells, and platelets, which perform different jobs. Consequently, ask which component needs attention.
Similarly, a CMP measures multiple substances. Your clinician may examine their pattern together when evaluating abnormal lab results.
Meanwhile, A1C reflects a longer period than a single glucose measurement. That difference helps explain why two blood sugar results may appear inconsistent.
Will I Need Another Blood Test?
Your clinician may recommend repeating a test, checking related measurements, monitoring a change, or arranging another evaluation. The next step depends on the particular finding.
Before leaving, ask when to complete any additional testing. Also, confirm preparation instructions and how you will receive the results. Avoid choosing a repeat-testing schedule yourself.
What Questions Should I Ask at My Follow-Up Appointment?
Use these questions to turn uncertainty into a clear conversation:
Which result needs attention, and why?
How does it compare with my earlier results?
Could my medicines or preparation affect it?
What should I do next?
Which symptoms should prompt an urgent call?
When should I expect another update?
Also, ask your clinician to explain unfamiliar terms in everyday language. Before the visit ends, repeat the plan in your own words to check your understanding.

1. Can I Have Abnormal Results and Still Feel Healthy?
Yes. However, feeling well does not tell you whether a finding needs follow-up. Ask the ordering clinician what the specific result means for you.
2. Do Abnormal Blood Test Results Mean Cancer?
No. Abnormal findings alone do not confirm cancer. Doctors use medical history, examination, and appropriate additional tests to investigate concerning findings.
3. Can Medicines Affect My Blood Tests?
Some medicines and supplements can affect certain results. Therefore, share your complete list and ask for test-specific instructions before changing anything.
4. Should I Fast Before Repeating a Blood Test?
Only fast when your care team instructs you to do so. First, confirm whether fasting applies to your test and how to handle your usual medicines.
5. What Should I Bring to My Appointment?
Bring the complete laboratory report, previous results if available, your medication list, and written questions. Also, note any symptoms you want to discuss.
