Lactate Scout+

Lactate Scout+ is a pocket-sized blood lactate analyzer for lab-accurate lactate measurements from tiny finger prick or earlobe samples. It provides lactate readings within ten seconds and requires only a 0.2 µl sample volume.

Up to 250 results can be stored on the device which also features stopwatch and count down timers for performance measurement. An integrated step test function and Bluetooth connectivity makes Lactate Scout+ the most advanced lactate meter in the market.

Lactate Scout+ has been designed to be used 'in the field' as a training companion for individuals or sports teams. Because lactate is an important measurement for many different types of athlete, the Lactate Scout+ operates in temperatures from 5-45 centigrade and in up to 85% humidity. An in-built compensation for hematocrit allows accurate measurements even at high (>50%) or low (<35%) hematocrit levels.

The operation of Lactate Scout+ is intuitive using scroll wheel navigation and a symbol-based menu. A high quality screen ensures excellent readability under changing light conditions and viewing angles.

Two 'AAA' batteries are all that is required to perform over 1,000 tests, and with pre-calibrated sensors and automated self-test, the Lactate Scout+ is the easiest and most reliable portable lactate analyzer available.

Designed and manufactured in Germany.

There are many uses of lactate in healthcare. Some of these are well established, for example lactate measurement in fitness and cardio training. As a world-leader in lactate, EKF has been closely involved in recently developed applications of lactate in obstetric medicine. On this page you can find out more about the increasingly important role of lactate in healthcare.

Regular endurance exercise has many benefits for health and well-being. It has been proven to lower systolic and diastolic blood pressure, improve insulin sensitivity and lower HbA1c levels, lower triglycerides and increase HDL-cholesterol. Regular power exercise, meanwhile, can increase insulin sensitivity.

The maximal fat oxidation rate is reached under long term aerobic conditions because this is when predominantly free fatty acids are used as the energy source. In contrast, under anaerobic conditions mainly carbohydrates are used for generating energy.

The measurement of lactate during step tests reveals the shift from aerobic (oxygen dependent) to complementary anaerobic (non-oxygen dependent) metabolism.  The knowledge of this ‘anaerobic threshold’ can be used for the definition of training intensities and conditions to achieve optimal fitness and weight reduction.

Furthermore, lactate testing can support a secure and efficient training avoiding critical over-exhaustion.

During birth a number of potential complications for mother and child may occur. These complications can lead to decreased oxygenation of the fetus and/or prolonged pain and injury of the mother. Monitoring mother and fetus closely provides decisions tools for an efficient and safe process of birth. 

Umbilical cord blood analysis, including lactate measurement, provides an indication of the acid–base balance of the infant at birth.  It is recommended in all high‐risk deliveries and, in some countries, is performed routinely after all deliveries. Cord blood lactate (CBL) has a predictive value for perinatal outcome and elevated lactate levels alert clinicians to undertake immediate intervention.

Monitoring fetal heart rate with a cardiotocograph (CTG) often indicates fetal distress but most of those neonates are not hypoxic at birth. A diagnostic test is required to confirm abnormal CTG values. In 1962 Saling et al / first described the use of pH measurement from fetal scalp during delivery as an indicator of hypoxia.

Measuring pH became a widely used clinical practice based on their findings. This approach is complicated by the need to collect a significant amount of blood (30-50 μl). This has led to reported sampling failure rates of 11-20%.

The alternative to this approach, fetal scalp lactate (FSL), is a simpler test which requires only a low volume of blood. Studies report significantly fewer failures in sampling with lactate analysis and no differences in short term neonatal outcome.

There are a number of causes for hyperlactatemia in critical ill patients. Sepsis, shock and trauma are the most common and serious ones. Pre-hospital measurements of lactate have been shown to improve the prediction of mortality, surgery and multi-organ failure.

General Safety note

Lactate Scout+ can be used as a monitoring or screening tool by qualified staff in various medical settings. The test results should only be used as a support for clinical decision making. As with any chemical reaction, the user must be aware of the potential effect on the result due to unknown interference from medication or endogenous substances. All patient results must be evaluated considering the total clinical status of the patient. Any decision for medical use of the device must be taken by the responsible clinician based on the specification of the device and local regulatory guidelines.
