A standalone platelet count — the clotting-cell number from a CBC on its own. For re-checking a low or high platelet result, or monitoring on a medication that affects platelets. A CBC with differential adds the other blood-count values for $7 more. Platelets (thrombocytes) are the cell fragments that plug a damaged vessel and start a clot; the count tells you whether you have enough of them to clot normally and not so many that clotting becomes a risk. Most people meet their platelet count as one line of a complete blood count, and a CBC is still the right first test — it costs $7 more here and adds red and white cell counts, hemoglobin and the differential. A standalone platelet count earns its place when the question is only about platelets: re-checking a single low or high value from a previous CBC, monitoring on a medication known to lower platelets, or following a diagnosis such as immune thrombocytopenia with a provider. Mildly low counts are common and often temporary (viral illness, some medications, alcohol); very low counts cause easy bruising and bleeding and need a clinician the same day. Mildly high counts are usually reactive — iron deficiency, inflammation, recent surgery or infection — which is why ferritin and CRP are the natural companions. Measured on an automated hematology analyzer at Quest or Labcorp (BioReference in New York and New Jersey); a clumped-platelet artifact can read falsely low, so an unexpectedly low result is usually repeated. ## Biomarkers measured - [Platelet Count](https://www.test-well.com/biomarkers/platelet-count) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $14.99 | $20.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $14.99 | $20.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $14.99 | $20.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.
