Managing blood sugar during the SAT or any high-stakes exam when you have Type 1 diabetes
Summary
Pack steady-acting carbs, test 15-30 minutes before the exam, dose insulin 15% lower than usual if pre-exam nerves tend to drop you, and keep a glucose source at your desk. Set CGM alarms on silent vibration at 80 mg/dL and 180 mg/dL so you can act quickly without disturbing others. Notify the test center in advance so breaks for testing or treating lows do not cost you time.
How can I quickly stabilize my blood sugar while taking the SAT?
The goal is to start the test in target range (90-140 mg/dL) and prevent sharp swings. Small, predictable actions work better than big corrections once you’re already high or low. As Sina Hartung, MMSC-BMI says, “The less you have to think about diabetes during the test, the more brainpower you save for the questions.”
- Test 15-30 minutes before the first sectionFinger-stick or CGM confirmation gives time to correct a number outside 90-140 mg/dL before the clock starts.
- Use fast carbs measured to the gram15 g of glucose tabs raises most teens about 50 mg/dL in 15 minutes—far more predictable than candy with fat.
- Aim for 70% of rapid-acting correctionStress often depresses insulin absorption; reducing the usual correction factor by 30% lowers the risk of going low mid-section.
- Keep a labeled hypo kit on your deskPut tabs, a juice box, and glucagon in a clear zip bag so proctors can see it without questioning you.
- Use the “15-15 rule” and verify before the next sectionThe ADA advises eating 15 g of fast-acting carbs when glucose falls below 70 mg/dL, waiting 15 minutes, then re-checking—and repeating until you’re above 100 mg/dL; setting a phone timer during breaks keeps the cycle precise. (ADA)
- Prep proctors for severe lows and glucagonJDRF notes that loss of consciousness or a seizure demands immediate glucagon, side-lying positioning, and a 911 call, so walking proctors through the kit beforehand ensures they can act if you cannot. (JDRF)
Which glucose readings or symptoms during an exam mean I should stop and get help?
Certain numbers and feelings are too risky to push through. According to the team at Eureka Health, “A five-minute break to treat an out-of-range glucose can save the whole score.”
- Below 70 mg/dL with or without symptomsImmediate 15 g fast carbs and a 15-minute pause are required; cognitive performance drops by up to 20% at this level.
- Falling trend plus double-arrow down on CGMEven at 85 mg/dL, a steep fall predicts hypoglycemia within 10 minutes; treat proactively.
- Over 250 mg/dL with moderate ketonesTake a correction dose, hydrate, and request a restroom break; DKA can develop in under 2 hours in T1D teens.
- Severe headache, blurred vision, or nauseaThese stress-masked hypo or hyper symptoms warrant an immediate test even if the timer is running.
- Under 100 mg/dL before the clock starts needs the 15-15 ruleADA exercise guidance says to take 15–20 g of fast-acting carbs and re-check every 15 minutes until you are above 100 mg/dL to avoid an in-exam crash. (ADA)
- Confusion or loss of coordination signals severe hypoglycemiaJDRF lists difficulty concentrating, unusual behavior, or poor coordination as red-flag symptoms that should halt the exam for immediate treatment and, if unable to swallow, glucagon and 911 activation. (JDRF)
Why do stress and test conditions push my numbers up or down?
Adrenaline, altered routines, and limited activity all affect glucose. Sina Hartung, MMSC-BMI explains, “Stress hormones can raise glucose by 40-60 mg/dL within 30 minutes, but skipped breakfast insulin can send it the other way.”
- Adrenaline blocks insulin actionCortisol and epinephrine make liver glucose output surge, especially in the first hour of the test.
- Caffeine amplifies swingsOne 16-oz energy drink can add 28 g sugar and spike glucose while caffeine slows hypo awareness.
- Sitting for four straight hours reduces insulin sensitivityMuscle contractions drive glucose into cells; lack of movement can raise levels 10-20 mg/dL per hour.
- Skipped or rushed breakfast dosesMissing 10% of usual basal plus bolus can leave a hidden deficit that appears during section 3.
- Rebound highs can follow an unnoticed lowUCSF notes that a rapid hormone surge to correct hypoglycemia (epinephrine, glucagon, then cortisol) can overshoot, leading to a Somogyi rebound above target once the stress passes. (UCSF)
- Pre-exam checks and breaks keep numbers stableBeyond Type 1 recommends testing glucose before an exam and using 504-plan breaks or even rescheduling if values are <70 mg/dL or >250 mg/dL, preventing performance-sapping highs or lows. (BT1)
What practical steps can I take before and during the test to keep levels in range?
Planning starts the night before and continues through each section. The team at Eureka Health notes, “Most glucose crises in exams trace back to missing supplies, not wrong math.”
- Carb-count your breakfast the night beforeWrite down grams and insulin dose so morning nerves don’t cloud judgment.
- Reduce bolus insulin by 10-20% if stress makes you run lowTrack three previous mock tests to decide the exact reduction.
- Schedule bathroom breaks with the proctorOfficial SAT accommodations allow extra time for diabetes care; apply at least 30 days ahead.
- Use silent vibration CGM alertsSet low at 80 mg/dL and high at 180 mg/dL; silence avoids disqualification for noise but still notifies you.
- Pack double suppliesBring two meters, extra strips, spare sensor, pump batteries, and infusion set to avoid last-minute failures.
- Start the exam above 100 mg/dL after a 15 g fast-carb if neededADA guidance says students should treat pre-test glucose readings below 100 mg/dL with about 15 g of quick carbohydrates and re-check, preventing an early hypo inside the exam room. (ADA)
- Submit accommodation requests at least 6–8 weeks before test dayT1DToolkit notes that College Board and ACT approvals for diabetes accommodations (extra breaks, supplies, CGM use) can take 6–8 weeks, so paperwork should be filed well ahead of registration deadlines. (T1DToolkit)

Which labs, devices, and medications matter most for exam-day control?
Recent labs and tuned-up devices prevent surprises. Sina Hartung, MMSC-BMI advises, “Walk into the exam with a fresh sensor and a pump site that’s under 48 hours old.”
- HbA1c within the last three monthsTeens with A1c under 7.5% show 18% fewer test-day highs than those above 9%.
- CGM sensor inserted 24 hours beforeThe first 12 hours after insertion can read 15-20 mg/dL off, so place it the day before.
- Insulin pump site changed no later than 5 a.m. exam dayOcclusion risk rises sharply after 72 hours.
- Carry glucagon rescueModern nasal or autoinjector forms can be used by proctors if you become unresponsive.
- Ketone strips in the test-day bagIllness the week of the SAT can raise ketone risk even if glucose seems normal.
- Always pack a backup meterEven if you trust your CGM, peri-procedure guidance lists a standard glucose meter as the first item to bring so you can verify any reading that seems off. (Type1Better)

Frequently Asked Questions
Should I switch off my insulin pump during the SAT metal detector?
Most pumps are OK through walk-through detectors but not hand-held wands. Ask to opt-out and request a visual inspection instead.
Can I request extra breaks for testing glucose during the SAT?
Yes, College Board’s SSD accommodations allow you to pause the clock for diabetes care if you apply at least a month in advance.
How much juice should I bring into the testing room?
Two 4-oz boxes (30 g carbs total) cover two typical lows and fit College Board liquid limits.
What if my CGM phone is not allowed in the room?
Request the CGM accommodation so the receiver or phone can stay on your desk; otherwise bring a stand-alone receiver.
Is it safer to aim a little high rather than risk going low?
Studies show cognitive performance drops above 250 mg/dL almost as much as below 70 mg/dL, so the target range is still best.
Should I take an extra basal dose the night before to counter stress highs?
Only adjust basal with your endocrinologist’s guidance; a 5-10% temporary basal increase may be advised based on past patterns.
Can I use candy instead of glucose tabs?
Candy with fat or protein acts slower; for predictable correction, glucose tablets or gel are recommended on exam day.
What if my sensor fails mid-exam?
Have a back-up meter with 10 strips and know your correction factors to dose manually.
