Blood taken from your arm can appear darker than expected, especially if it's venous blood, which is typically a deep red or dark purple due to lower oxygen levels compared to arterial blood. The darker color is normal and reflects the deoxygenated state of the blood returning to the heart. However, if there are unusual characteristics or significant changes in color, it’s best to consult a healthcare professional for advice.
