Ordering the Stained Blood Film Test
The Stained Blood Film Test helps detect blood-borne infections and abnormalities in red and white blood cells, platelets, and parasites. This test uses both Giemsa and Modified May-Grünwald stains to provide a detailed look at blood samples, making it useful for identifying infections like malaria, babesia, and tick-borne diseases. Interestingly, the Modified May-Grünwald stain was developed to improve the detection of certain blood-borne infections that may be missed by standard stains.
Ordering this test can help you:
- Identify the presence of parasites such as malaria or babesia in the blood.
- Detect abnormal shapes or sizes of red blood cells, which can point to conditions like sickle cell disease or anemia.
- Spot early signs of bacterial or viral infections that may not show up in other tests.
- Monitor changes in white blood cell counts that could signal immune system activity or inflammation.
- Assess platelet levels to help explain unexplained bruising or bleeding.
Who Should Consider Blood Smear Analysis
People who have ongoing fatigue, unexplained fevers, or recurring chills after spending time outdoors may benefit from this test. For example, someone who recently returned from a trip to a region where malaria is common and now feels weak and feverish could use this test to check for parasites in their blood.
Ordering this test may also be helpful in these situations:
- After a tick bite, especially if symptoms like joint pain or rash develop.
- When there is unexplained jaundice or yellowing of the skin.
- For those with a history of anemia who notice new or worsening symptoms.
- When a doctor suspects a co-infection with Lyme disease or other vector-borne illnesses.
- In cases where a person has persistent low-grade fever and night sweats, which can sometimes be linked to hidden blood infections.
This test can help pinpoint the cause of symptoms by showing if there are parasites, abnormal blood cells, or signs of infection in the blood. Delaying this test could mean missing early signs of treatable infections or blood disorders, which may lead to more complicated health issues later.
Preparing for Blood Parasite and Cell Morphology Screening
Fasting is not required before this test, so you can eat and drink as usual. Always follow any instructions your doctor or healthcare provider gives you to make sure your sample is collected and processed correctly.
Labs Included When Ordering Your Stained Blood Film Test
| Test Name | Reference Range | Significance | Low and High Levels of Stained Blood Film Test |
|---|---|---|---|
| Red Blood Cell Morphology | Normal shape and size | Shows if red blood cells are the right shape and size. Abnormalities can point to anemia, sickle cell, or other blood disorders. |
High levels mean more abnormal cells, which may signal sickle cell disease or severe anemia.
Low levels mean mostly normal cells, which is expected in healthy blood. |
| White Blood Cell Count and Appearance | 4,000–11,000 | Checks the number and look of white blood cells. Changes can show infection, inflammation, or immune system problems. |
High levels mean possible infection or inflammation.
Low levels mean possible immune suppression or bone marrow issues. |
| Platelet Count and Clumping | 150,000–450,000 | Shows if platelets are present in normal numbers and if they clump together. This helps explain bruising or bleeding problems. |
High levels mean risk of blood clots or inflammation.
Low levels mean risk of bleeding or bruising. |
| Parasite Detection (Malaria, Babesia, etc.) | None detected | Looks for parasites in the blood, such as malaria or babesia. Early detection helps guide treatment and prevent complications. |
High levels mean active infection with parasites.
Low levels mean no parasites found, which is normal. |
| Bacterial and Viral Inclusions | None detected | Checks for signs of bacteria or viruses inside blood cells. This can help diagnose infections like ehrlichiosis or bartonella. |
High levels mean possible active infection.
Low levels mean no infection detected. |
| Hemoglobin Content | 13.5–17.5 (men), 12.0–15.5 (women) | Measures the amount of hemoglobin in red blood cells. Low levels can point to anemia or blood loss. |
High levels mean possible dehydration or lung disease.
Low levels mean possible anemia or bleeding. |
Reference ranges may change slightly based on updates from the laboratory or new clinical guidelines.
