Why LEE-LOK?

...our high quality products ensure that you get the right results, each and every time.

Peripheral blood examination and other routine laboratory procedures don’t always provide enough information for diagnosis of hematologic disease. A bone marrow examination is performed in nearly every patient with a suspected hematologic malignancy. Bone marrow examination is also part of the staging process for newly-diagnosed patients with a malignant lymphoma or for patients with solid tumors undergoing evaluation for bone marrow transplantation.

Occasional patients also require bone marrow for special studies, such as cytogenetic analysis, flow cytometry, or microbiological analysis. Our Lee-Lok needles cover every application relating to bone marrow examination and our high quality products ensure that you get the right results, each and every time.
