Every marker varies a little from one blood test to the next, even when nothing about your health has changed: the time of day, what you ate, how the sample was handled. Studies of healthy people measure how much. For this marker it's about 2.5% within one person (Gupta et al., Scand J Clin Lab Invest 2019 (EFLM BV database)). Adding a typical lab's measuring error, a move smaller than about 8% between two draws is within that normal wobble. Only a bigger move is likely a real change, so that's the only kind Helse calls “better” or “worse.”Lab reference rangeOutside the lab's range

One blood test can land a little above or below your usual level for reasons that aren't about your health — for this test, within about ±5.5%. That's its published variation — Gupta et al., Scand J Clin Lab Invest 2019 (EFLM BV database) — plus a typical lab's measuring error. So close to a line, one result can't say which side your usual level is on, and the colours mix in proportion to how likely each side is. Further from a line, the colour is clear.- 19 May 202613.3 g/dLNormalLab range 11.1–15.9
