High Hemoglobin at Red Cross

[tjlab]

I have a quick question. I just gave blood at the red cross and my Hemoglobin was 17.7. I drank 32oz water 30 minutes before I went to give blood. Here is my question. Per my past blood draws at the doctors office, which you will see below, does this seems like an inaccurate measurement? Any thoughts? I dropped my Test Cyp dosage to 80mg IM once weekly (from 100mg) over the past 3 weeks.

3/12/2018 - Hemoglobin (15.6) Hematocrit (47.5)
11/5/2018 - Hemoglobin (16.1) Hematocrit (47.3)
2/11/2019 - Hemoglobin (16.5) Hematocrit (47.9)
3/19/2019 - Hemoglobin (16.7) Hematocrit (47.9)
4/3/2019 - Hemoglobin (17.7) RED CROSS DONATION

Any thoughts?

I'd defer to what comes from a CBC test and not the finger stick. Different methods being used are tough to hold side-by-side.
