Platelets are small cell fragments that help your blood clot. The count shows whether you have enough, and an unusual number is often an early clue to something else going on.
Platelet count. The number of platelets in the blood. They gather at a cut or injury and help form a clot to stop bleeding.
Mean platelet volume (MPV). The average size of your platelets, measured on the same full blood count. It can help explain why a count is high or low.
Platelets are made in the bone marrow and last about a week to ten days. A count that is too low can make bruising and bleeding easier. A count that is too high can, in some people, raise the risk of clots. Most unusual results are mild and have an everyday cause, which is why the count is read with the rest of the blood count and your inflammation markers.
Low platelets are commonly linked with viral infections, heavy drinking, liver conditions, some medicines and pregnancy. High platelets are commonly linked with low iron, recent infection, inflammation and recovery from surgery or injury. Sometimes platelets clump together in the sample tube, which makes the count look falsely low. A repeat test usually sorts that out.
Platelets are reported as x10^9 per litre. A count of roughly 150-400 x10^9/L is a common adult range, though some labs use up to 450. Reference ranges vary by lab.
A mildly low count often follows a viral infection and is rechecked after a few weeks. It can also be linked with alcohol, liver conditions or some medicines. A very low count, or one with unusual bleeding or bruising, needs prompt follow-up with your own doctor.
A raised count is most often a reaction to low iron, infection or inflammation, and tends to settle once the cause is dealt with. A count that stays high without a clear reason is worth following up.
Reference ranges differ between labs, and a single result is a snapshot. Your consultant reads every value against your history and the rest of the screen, not in isolation.
This test is part of Baseline’s full blood screen: 122 parameters across ten systems from one draw, for AED 850, with results in 48 hours. It is not sold as a single test, because the result means more next to everything else.
Ranges are the lab’s own. Your consultant goes through what they mean with you.
Your results arrive in the Baseline app, every marker against the lab’s own range, checked by your consultant before you see them. The values above are an example.

Reading is not a diagnosis. A consultation goes through your history with you and tells you plainly whether a program fits, including when it does not. AED 350, credited in full against your first order.
