From the Research
For a 22-year-old female with giant platelets on blood work but a normal peripheral smear, I recommend monitoring her platelet count and function over time without immediate intervention. This approach is based on the most recent and highest quality study available, which emphasizes the importance of a thorough evaluation and monitoring in cases of suspected platelet-related disorders 1. You should obtain a complete blood count with platelet parameters to assess if there are any quantitative abnormalities, and consider platelet function testing if there are any bleeding symptoms. A detailed personal and family history focusing on bleeding tendencies is important, as giant platelets can be associated with inherited platelet disorders like Bernard-Soulier syndrome or May-Hegglin anomaly.
Some key points to consider in the evaluation of this patient include:
- The role of peripheral blood smear examination in the evaluation of suspected platelet-related disorders, as highlighted in a recent review 1
- The potential for giant platelets to be associated with inherited platelet disorders, as discussed in a study on hereditary giant platelet syndromes 2
- The importance of monitoring platelet count and function over time, as suggested by a study on the use of the Platelet Function Analyzer (PFA)-100 test in clinical practice 3
- The need for a thorough evaluation and monitoring in cases of suspected platelet-related disorders, as emphasized in a recent study on the evaluation of suspected platelet-related disorders in children 1
If the patient is asymptomatic with normal platelet counts and no bleeding history, this may represent a benign finding or laboratory artifact. However, if she has low platelet counts, bleeding symptoms, or a positive family history, referral to a hematologist would be appropriate for further evaluation. Giant platelets can sometimes be seen in healthy individuals or may indicate an underlying platelet production abnormality, but the normal peripheral smear is reassuring. Routine follow-up in 3-6 months with repeat CBC would be reasonable to ensure stability of findings.
