What it measures
This test measures a natural sugar that can drop when your blood sugar spikes, such as after meals. It can reflect the past couple of weeks, a shorter window than a typical blood sugar average.
Why it matters for women
PCOS and diabetes that started during a past pregnancy can both raise the chance of developing diabetes later. This test can catch after-meal sugar spikes that a long-term average may miss. Pregnancy changes how the kidneys handle sugar, so results are harder to read then.
You might check it if…
- you had diabetes during a past pregnancy
- you live with PCOS or insulin resistance
- a doctor wants to see after-meal spikes your average may miss
What your result may mean
High 1,5-AG: what it may mean
High 1,5-AG (1,5-anhydroglucitol) may be uncommon and may need no action on its own, because clinicians can read this marker mainly through its lower range. A value in the upper range may mean your blood sugar has stayed below the point where sugar spills into urine over the past 1 to 2 weeks. It can't rule out diabetes or prediabetes, so a clinician may still look at your glucose and A1c. Pregnancy can change how the kidneys handle sugar, so results can be harder to read then.
Low 1,5-AG: what it may mean
Low 1,5-AG may mean your blood sugar has been spiking after meals enough to spill into urine, even when fasting glucose and A1c look controlled. It can reflect the past 1 to 2 weeks, a shorter window than A1c. PCOS and past diabetes in pregnancy can raise the chance of these spikes. Diabetes medicines that make the kidneys pass sugar (SGLT2 inhibitors), advanced kidney disease and pregnancy can also lower this result. High blood sugar may bring thirst and frequent urination, though many people may not notice spikes at all.
