Your Follow-Up Tests: What to Expect After Anemia Diagnosis - Family Medicine

Share to:

Medical consultation


Hello Doctor, I previously had a health check-up and found that I have anemia and trace protein in my urine (-/+).
Therefore, I consulted a family medicine doctor for further evaluation.
The doctor ordered emergency lab tests (CBC-I) and outpatient tests (urinalysis, stool test, serum iron, etc.) and advised me to return for follow-up about a month later.
I would like to ask if these tests are done on the same day as the follow-up appointment, or do I need to go for testing the day before? (The appointment is scheduled for the morning, and no specific instructions were given.) Thank you.

Hello: Your doctor has ordered a complete blood count (CBC) and tests for urine, stool, and serum iron.
The results for these tests typically take about half a day to one or two days to process, depending on the hospital's testing procedures.
Please make sure to go to the hospital for blood draw, urine test, and stool sample submission at least three days before your follow-up appointment, so that the reports will be available on the day of your visit.

When you receive a diagnosis of anemia, it is essential to understand the follow-up tests and what to expect. Anemia can be caused by various factors, including nutritional deficiencies, chronic diseases, or bone marrow disorders. The follow-up tests your doctor has ordered, such as a Complete Blood Count (CBC), urinalysis, stool tests, and serum iron studies, are crucial for determining the underlying cause of your anemia and guiding appropriate treatment.

1. Understanding the Tests:
- Complete Blood Count (CBC): This test measures various components of your blood, including red blood cells, hemoglobin, hematocrit, white blood cells, and platelets. It helps assess the severity of anemia and can provide clues about its cause.

- Urinalysis: This test checks for the presence of protein, blood, or other substances in your urine, which can indicate kidney issues or other systemic problems.

- Stool Tests: These tests can check for hidden (occult) blood in your stool, which may suggest gastrointestinal bleeding, a common cause of iron deficiency anemia.

- Serum Iron Studies: These tests measure the amount of iron in your blood and how well your body is using it. They help determine if your anemia is due to iron deficiency.

2. Timing of the Tests:
- Typically, these tests can be done on the same day as your follow-up appointment, but it is often recommended to have them completed beforehand. This allows your doctor to review the results during your visit and make informed decisions about your treatment plan.

- If your appointment is in the morning, it is advisable to schedule your blood tests for the same day, ideally early in the morning, to ensure that the results are available for your doctor to review during your appointment. However, for tests like stool samples, you may need to collect those at home prior to your visit.

3. Preparation for the Tests:
- Some tests may require specific preparations, such as fasting for a certain period before blood draws. Your healthcare provider should inform you if any special instructions are necessary.

- For urine tests, you may need to collect a sample at home or provide a fresh sample at the clinic, depending on the type of urinalysis being performed.

4. Follow-Up and Next Steps:
- After your tests, your doctor will discuss the results with you and determine the next steps based on the findings. If the tests indicate a specific cause of your anemia, such as iron deficiency, your doctor may recommend dietary changes, supplements, or further investigations.

- If the tests do not reveal a clear cause, additional testing may be necessary, including more specialized blood tests or imaging studies.

5. Importance of Communication:
- If you have any uncertainties about when to have your tests done or how to prepare for them, do not hesitate to reach out to your healthcare provider's office. They can provide clarification and ensure you are adequately prepared for your follow-up appointment.

In summary, understanding your follow-up tests after an anemia diagnosis is crucial for effective management. Ensure you have your tests done in a timely manner, preferably before your follow-up appointment, to facilitate a comprehensive discussion with your doctor regarding your health status and treatment options.
