| patient if the device gets too warm, they'll ding it.
| Diagnostic software powering these devices are scrutinized by
| the FDA, too.

| Abstract: _The development of a cost-efficient and sensitive
| platform for biochemical analysis of blood serum and its
| realization in the low resource areas is one of the imperative
| challenges to establish a robust healthcare ecosystem. The
| present work demonstrates the design of a universal platform,
| capable of performing all biochemical analyses of blood serum by
| measuring the absorbance of light through the test sample. To
| verify the working of the developed platform, the concentration
| of glucose was estimated in blood serum. The detection of glucose
| has been accomplished in a linear range of 1 mg /dL to 400 mg/dL
| with detection of limit 1 mg/dL (R2 = 0.9875, n=3). The stability
| analysis demonstrates improved stability in the output as
| compared to the conventional analyzer with an average standard
| deviation of 0.32 calculated for n=5. Human blood samples were
| tested with the developed platform and the results were in line
| with the pathology laboratory. The developed platform offers the
| advantages of automation, low cost, portability, simple
| instrumentation, flexibility, and an easily accessible interface.
| Due to the use of a huge processing capability processor, the
| analysis time reduces to half a minute which yields fast analysis
| and high throughput. The stability and accuracy also improve
| owing to the employment of high-resolution electronics
| components. Overall, the proposed framework is an attractive
| solution to be incorporated in the low resource area as a
| universal platform for all biochemistry analysis simply by
| varying the wavelength of light and reagent._
