How to run your own lactate test: the complete guide

With a portable lactate meter, a consistent protocol and a clean analysis workflow, you can run a useful step test without a lab.

Equipment for a self-administered lactate test

You need a portable lactate meter, a repeatable exercise protocol and software for interpreting the measurements. Use a cycle ergometer or treadmill that lets you hold the workload steady while sampling.

  • A meter such as Lactate Scout Sport, Lactate Pro 2, Nova Lactate Plus or Lactate Express
  • Compatible lancets and test strips
  • A measured workload in watts, speed or pace
  • LactateThreshold for analysis; optionally a heart-rate strap

The step-test protocol

Measure blood lactate while increasing the workload in defined stages. The protocol in the German guide uses 3–5 minutes per stage, with at least 3 minutes before sampling.

  • Cycling increments: 20–30 watts
  • Running increments: 0.5–1 km/h or 15–20 seconds/km
  • At least 5 stages, ideally 7–9
  • Sample during the final 30 seconds of each stage

Sample quality matters

Sampling errors can distort the curve and estimated thresholds. Warm the fingertip or earlobe for at least 5 minutes, discard the first drop and let blood flow without squeezing the sampling site. Fill the strip promptly and follow the meter manufacturer’s calibration instructions.

Enter the complete stage measurements

Pair each lactate value with its corresponding watts or pace. Add heart rate if available. The analysis uses the relationship across stages to calculate LT1, LT2 and five training zones; a meter reading alone does not define these zones.

Avoid the common protocol mistakes

The guide calls for 10–15 minutes of easy warming up, an opening stage clearly below LT1 and sufficiently long stages. Keep the sampling site warm. Its preparation example also uses a three-hour interval after eating; consistent preparation matters when comparing tests.

Why you can trust the analysis

LactateThreshold does not turn measurements into false precision. The app shows the curve, method comparison, plausible thresholds and the limits of your test protocol transparently.

Frequently asked questions

Can I perform the test alone?+
With practice, especially on a cycle ergometer where the workload stays fixed during sampling. For running, a helper or a controlled treadmill pause can make sampling easier.
When should I repeat it?+
The guide suggests 8–12 weeks after a training block or before a season. For an initial baseline, it suggests a comparison after about three months.
What costs does the original guide assume?+
Its example uses EUR 300–450 for a meter, EUR 2–8 per measurement and free software analysis, compared with EUR 150–300 for a lab test. These are the article’s example estimates; check current meter and strip prices before budgeting.

Lactate Pro 2 vs. EKF Lactate Scout Sport

Both meters are proven options for field testing. The right choice depends on workflow, sample volume, cost and availability.
