Large and small platelets—(When) do they differ?
网页2020年2月28日 · Size distribution of platelets in one individual is determined by the platelet distribution width (PDW), referring to the curve width at the level of 20%. To quantify large platelets, automated cell counters can calculate the platelet large cell ratio (P-LCR), defined as proportion of platelets larger than 12 fL 21 (Figure 2).
Platelet - Wikipedia
网页Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [1] .

网页2020年6月1日 · WHAT IS A MEAN, A LARGE AND A SMALL PLATELET? Max Schultze described human platelets as individual spherules measuring 1‐2 µm being six to eight times smaller than red cells under the microscope in 1865. 14 Microscopy of May‐Grünwald‐Giemsa stained blood smears revealed a mean diameter of 1.7 ± 0.1 µm for resting platelets of healthy subjects.10.

网页The platelet is a circulating anuclear fragment of a bone marrow megakaryocyte, 3 to 4 μm in diameter, with limited synthetic capability. The mean normal platelet count is between 250,000 and 260,000 cells/mm3, although there is a wide range of accepted normal values in most laboratories that extend as low as 150,000 to as high as 400,000/mm3.

What Are Platelets? Function & Anatomy - Cleveland Clinic
网页2024年8月26日 · Platelets, also called thrombocytes, are tiny cell fragments in your blood that help with clotting. Platelets are your body’s natural bandage to stop bleeding if you’re injured. Just a single drop of your blood contains tens of thousands of platelets. It’s important that you have enough (but not too many) of them.
