In short

Platelets, or thrombocytes, are tiny cell fragments in your blood that clump together to stop bleeding. When a blood vessel is injured, platelets gather at the site and help form a clot.

The platelet count measures how many you have in a set volume of blood. It is a core part of the complete blood count and a key check on your blood's ability to clot.

Blood Health (CBC & Iron)

Reviewed against DGKL reference practice.

Why test this?

A platelet count helps assess your risk of bleeding or clotting. A low count (thrombocytopenia) can raise the risk of bruising and bleeding and may follow some infections, medications, immune conditions, or bone marrow problems.

A high count (thrombocytosis) can occur with inflammation, iron deficiency, or, less often, a bone marrow disorder, and can increase clotting risk. Trends over time are often as informative as a single value.

What is a normal result?

Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.

Adult reference values as used by Aniva. Ranges are guidance and can vary by laboratory and method.

Group	Normal range	Optimal range
Men	135 to 317 ×10⁹/L	190 to 300 ×10⁹/L
Women	157 to 371 ×10⁹/L	190 to 300 ×10⁹/L

Your Aniva report reads your result against these values together with your age, sex and the rest of your panel.

Ranges are guidance and vary by lab and assay, aligned with DGKL practice. Always read your result against your own lab's reference interval.

What insights will this test give you?

Whether your clotting cells are in a healthy range.
An early flag for easy bruising or bleeding, or for raised clotting risk.
A value your concierge reads with the rest of your blood count and any inflammation markers.

What can affect this result?

What can skew the result

Platelets can clump in EDTA tubes in some people, giving a falsely low count that a blood film can correct. Recent exercise can raise the count briefly. Very small platelets or clots in the sample can affect automated counting.

Best interpreted with

Read together with the rest of the complete blood count, and with inflammation and iron markers when the count is high or low.

Common questions

What do my results mean? Higher counts can occur with illness or iron lack; lower counts can follow medicines or infections. Your clinician will interpret trends with your CBC.

Do I need to fast for this test? No. You can eat and drink normally unless your clinician requested other fasting tests.

What can affect my platelet count? Aspirin, antiplatelet drugs, anticoagulants, chemotherapy, alcohol, infections, hard exercise, pregnancy, dehydration, and sample clumping can influence counts.

How often should I check my platelets? Often during routine checkups as part of a CBC. Frequency depends on symptoms, conditions, or medications being monitored.

How long do results take? Results are usually ready in about 7 days.

What should I discuss with my clinician? Bleeding or bruising, recent infections, all medicines and supplements, alcohol use, and any planned surgery or dental work.
