The National Academy of Sciences concluded “Tissue concentrations of carotenoids are the best biological markers for
consumption of fruit and vegetables.”
If we were to liken a carotenoid to a grain of sand, a typical scan session would be like searching for 40 “special” grains of sand in an
area covered with 2.4 trillion grains of normal sand.
If you lined up every grain of that sand, then it would cover the Dune of Pilat in France, twice!—with a 1mm deep layer of sand.
Imagine you have a super-camera that could scan the 2 dunes of sand all at once and a computer in the camera counted the special grains hidden among the 2.4 trillion other grains.
Such a super-camera would not be able to tell you the exact number every time. Instead it would give an estimate of how many of the special grains the computer thinks it sees.
So rather than spending your entire life counting the grains, you use your super-camera to take a picture to find the 40 special gains and the computer tells you there are 37 special grains.
You decide to take the picture again just to be sure. This time the computer tells you there are 44 grains. Neither score is perfect, but both scores give you a good idea of the true value.
All equipment is subject to variability when performing a measurement. It is not a question of whether there is going to be variation. It is a question of how much variation exists.It can only be reduced and managed through proper usage, maintenance, calibration, and other methods.
1. Is the BPS “more variable” than other similar equipment?
2. Is the S3 BPS “more variable” than the S2?
QUESTIONS:
Pharmanex R&D conducted a research project to evaluate S3 device variability.
3,600 total scans
10 different S3 devices
30 scans on each device per session
3 different scan sessions per subject in a 7 day period
4 different subjects
The S3 is marketed to have an acceptable device variability of 9,000 points (or 3 ‘color shades’). This is roughly a 15% variability. Testing of the device shows that the S3 performs at or above this expectation in 85% of all cases. Other experiments have shown the S3 regularly outperforms this standard.

SOME THINGS THAT CAN GIVE YOU A “BAD READING”
An important way to reduce BPS variability is to be as repeatable and consistent as possible in hand placement on the scanner probe. Inconsistent hand placement is a known variable that can increase score fluctuation.
The experiment below tests the variability of a subject when moving the hand only 0.5 cm (5mm) away from the target hand point for scanning.

BPS scores can also vary depending on the amount of hand pressure the subject uses while scanning.
The experiment below tests how much score can vary when a subject uses ‘light’ hand pressure versus ‘hard’ hand pressure.

BPS scores can also vary depending on the amount of hand pressure the subject uses while scanning.
The experiment below tests how much score can vary when a subject uses ‘light’ hand pressure versus ‘hard’ hand pressure.
Hand Pressure
Higher hand pressure appears to have a tendency to increase scanner scores.However, this effect does not appear to be universal for all subjects. The person with the highest score also had the least amount of pressure variability.Hand pressure is an important variable to manage for some individuals as a means of controlling score variability.
The temperature of the BPS, the environment in which the BPS is stored, and the temperature where it is operated can all impact score variability.
Experiments have been conducted to measure the effect of temperature on BPS performance.

What to do if someone’s score seems to be “too high” or “too low:
1.Scan three times or more
2.Take an average to determine an estimate for the THV (True Hand Value)

3-SCAN AVERAGE
• Both the S2 and the S3 devices have variability levels that are superior or comparable to other similar devices.
• There are other existing carotenoid tools which have less variability than the S2 or S3. This includes High Performance Liquid Chromatography (HPLC). These tools are considered to fall outside the scope of the S3 device (laboratory analysis).
• The S3 is not more variable than the S2. Repeated experiments have shown a tendency for the S3 to be slightly less variable than the S2.
Great improvements have been made over the years, making the scanner faster, portable, and more convenient.
The S3, like other devices, is subject to variability which, with proper care, can be managed and also taught to customers.
With proper treatment, best practices, and timely calibration, the S3 can be a very effective tool to assess the amount of carotenoids
incorporated in the skin and promote one’s business.
