How do you evaluate a peripheral blood smear?
Peripheral blood smear can be used for estimation of manual blood counts. With the advent of automated cell counters which are more reliable and accurate, manual differential counts of white blood cells using PBF is gradually fading in routine haematology laboratory practice.
What is blood smear interpretation?
What do the results mean? A blood smear is considered normal when your blood contains a sufficient number of cells and the cells have a normal appearance. A blood smear is considered abnormal when there’s an abnormality in the size, shape, color, or number of cells in your blood.
How do you read CBC results?
When you get your report, you’ll see two columns: a “reference range” and your results. If your results are inside the reference range, they’re considered normal. If your results are higher or lower than the reference range, they’re abnormal.
What is a normal platelet count?
A normal platelet count in adults ranges from 150,000 to 450,000 platelets per microliter of blood. A platelet count of less than 150,000 platelets per microliter is lower than normal. When you have a low platelet count, you may have trouble stopping bleeding.
What is the normal range for blood test results?
Lab results are often shown as a set of numbers known as a reference range. A reference range may also be called “normal values.” You may see something like this on your results: “normal: 77-99mg/dL” (milligrams per deciliter). Reference ranges are based on the normal test results of a large group of healthy people.
What is normal CBC values?
These parameters were determined for approximately 1500 to 2000 individuals ages 20 to 80 (varies slightly by category).

What are the 3 functions of platelets?
In addition to regulation of hemostasis in the vessel, platelets have also been shown to play an important role in innate immunity as well as regulation of tumor growth and extravasations in the vessel. These primary functions of the platelet represent its normal function and versatility in circulation.
What if platelet count is high?
If your platelet count is too high, blood clots can form in your blood vessels. This can block blood flow through your body. Thrombocythemia refers to a high platelet count that is not caused by another health condition. This condition is sometimes called primary or essential thrombocythemia.
How do I read my blood type results?
If your red blood cells have:
- The A antigen, you have type A blood. The liquid portion of your blood (plasma) has antibodies that attack type B blood.
- The B antigen, you have type B blood.
- Neither the A nor B antigen, you have type O blood.
- Both the A and B antigens, you have type AB blood.
What cancers are detected by blood tests?
Blood tests can be useful in all types of cancer, particularly blood cancers such as:
- Hodgkin lymphoma.
- Leukemia.
- Non-Hodgkin lymphoma.
- Multiple myeloma.
What indicates infection in a blood test?
Complete blood count (CBC). An increased white blood cell (WBC) count (or in some cases a decreased WBC count) may indicate infection.
What is the another name of platelets?
Platelets, or thrombocytes, are small, colorless cell fragments in our blood that form clots and stop or prevent bleeding.
Which organ makes platelets?
Platelets are produced in your bone marrow. Factors that can decrease platelet production include: Leukemia and other cancers. Some types of anemia.
What is normal platelet count?
Which cancers cause high platelet count?
A recent increase in the platelet count was associated with risk of colon cancer (OR, 5.52; 95% CI, 5.21-5.86), lung cancer (OR, 4.77; 95% CI, 4.51-5.04), ovarian cancer (OR, 7.23; 95% CI, 6.12-8.53), and stomach cancer (OR, 5.51; 95% CI, 4.82-6.29) (Figure 3 and eTable 7 in the Supplement).
What is blood type A positive?
If your blood is A positive (A+), it means that your blood contains type-A antigens with the presence of a protein called the rhesus (Rh) factor. Antigens are markers on the surface of a blood cell. According to the American Red Cross, this is one of the most common blood types.
What is positive and negative blood group?
Rh factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you’re Rh positive. If your blood doesn’t have the protein, you’re Rh negative. The “+” or “–” you might see after your blood type refers to Rh positive or Rh negative.
How do you read a blood report?
