Is 130 a low 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
. If your blood platelet count falls below normal, you have thrombocytopenia.
What is the significance of measuring platelet count?
A platelet count is a
lab test to measure how many platelets you have in your blood
. Platelets are parts of the blood that helps the blood clot. They are smaller than red or white blood cells.
How is platelet count calculated?
An estimated platelet count can be done quickly with a blood smear evaluated at 100× magnification. At this magnification, the platelet count/μL of blood can be approximated by
multiplying the number of platelets seen in one microscope field by 15,000
.
What is the unit for platelet count?
Platelet count: The calculated number of platelets in a volume of blood, usually expressed as
platelets per cubic millimeter (cmm)
of whole blood.
What are the signs of low platelets?
- Easy or excessive bruising (purpura)
- Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs.
- Prolonged bleeding from cuts.
- Bleeding from your gums or nose.
- Blood in urine or stools.
Can you live with low platelets?
A low platelet count may also be called thrombocytopenia. This condition can range from mild to severe, depending on its underlying cause. For some, the symptoms can include severe bleeding and are possibly fatal if they’re not treated.
What are the 3 functions of platelets?
The main function of platelets, the maintenance of hemostasis, depends on three of their properties, the endothelial supporting function of platelets,
the ability to form hemostatic plugs and to release lipoprotein material (platelet factor 3)
.
What cancers cause high platelets?
8 This is known as paraneoplastic thrombocytosis. This is more common in solid tumors like
lung cancer
, hepatocellular (liver) carcinoma, ovarian cancer, and colorectal cancer. Elevated platelet count can also be seen in chronic myelogenous leukemia (CML).
What are the symptoms of high platelets?
The signs and symptoms of a high platelet count are linked to blood clots and bleeding. They include
weakness, bleeding, headache, dizziness, chest pain, and tingling in the hands and feet
.
How accurate are platelet counts?
The acceptable range to ensure that platelet counts are clinically reliable in EQA may be set at
10% to 15% of the target or assigned value
,

which would give an approximate range of ± 5 × 10

What is a manual platelet count?
Manual platelet counts
Platelet counts can be done manually with a commercial diluting system, hemocytometer, and a microscope. These counts are less accurate than automated counts, because platelets can be difficult to distinguish from debris. Platelet clumping will also decrease the hemocytometer platelet count.
Does platelet count change with age?
Platelet count decreases with age
, and women have more platelets than man after puberty.
What volume is 1 unit of blood?
The volume of one unit of RBCs contains
approximately 200mL red blood
cells, 100 mL of an additive solution, and ~30mL plasma, with a hematocrit approximately 55%.
How much does 1 unit of platelets raise?
Request for Blood and Blood Components form To prevent or treat bleeding due to thrombocytopenia and/or platelet dysfunction. 1 unit will increase platelet count
~ 6,000/μl
(average size adult **).
Is 500 a high platelet count?
Normal platelet counts are in the range of 150,000 to 400,000 per microliter (or 150 – 400 x 109 per liter), but the normal range for the platelet count varies slightly among different laboratories. An elevated platelet count is known as
thrombocytosis
.
