High Hemoglobin at Red Cross

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

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
