The SWIR detector can include a lens configured to enable the SWIR detector to capture an image of a skin testing area of a patient. The SWIR detector can be configured to detect a wheal formed on the skin testing area of the patient. Exemplary embodiments are also directed to methods of reading a skin test and skin test reading systems. ## Claims ### Claim 1 An allergy skin test reading device, comprising: a short wave infrared (SWIR) detector including a lens configured to enable the SWIR detector to capture an image of an allergy skin testing area of a patient; wherein the SWIR detector is an indium gallium arsenide (InGaAs) detector configured to detect wavelengths between (i) 1,350 nm and 1,450 nm, and (ii) 1,600 nm and 1,800 nm, to detect a wheal formed on the allergy skin testing area of the patient in response to an allergen introduced to the allergy skin testing area. ### Claim 2 (depends on 1) The allergy skin test reading device of claim 1, wherein the SWIR detector is configured to detect the wheal formed on the allergy skin testing area of the patient during an allergen test. ### Claim 3 (depends on 1) The allergy skin test reading device of claim 1, wherein the SWIR detector comprises a filter configured to isolate or remove predetermined wavelengths of light associated with the allergy skin testing area. ### Claim 4 (depends on 3) The allergy skin test reading device of claim 3, wherein the filter is a bandpass filter that is configured to obscure veins in the allergy skin testing area to enhance detection and visibility of the wheal formed on the allergy skin testing area of the patient. ### Claim 5 (depends on 1) The allergy skin test reading device of claim 1, further comprising a visual wavelength detector including a lens configured to enable the visual wavelength detector to capture an image of the allergy skin testing area of the patient. ### Claim 6 (depends on 1) The allergy skin test reading device of claim 1, further comprising a processing device configured to analyze the wheal in the captured image of the allergy skin testing area of the patient and output a dimension associated with the wheal. ### Claim 7 (depends on 12) The allergy skin test reading device of claim 12, wherein the dimension associated with the wheal is a wheal diameter. ### Claim 8 (depends on 1) The allergy skin test reading device of claim 1, further comprising a graphical user interface configured to display the captured image of the allergy skin testing area of the patient with the wheal. ### Claim 9 A method of reading a skin test for allergy testing, comprising: providing an allergy skin test reading device, the allergy skin test reading device including a short wave infrared (SWIR) detector in the form of an indium gallium arsenide (InGaAs) detector including a lens; capturing an image of an allergy skin testing area of the patient with the InGaAs detector; and detecting wavelengths between (i) 1,350 nm and 1,450 nm, and (ii) 1,600 nm and 1,800 nm, with the InGaAs detector to detect a wheal formed on the allergy skin testing area of the patient in response to an allergen introduced to the allergy skin testing area. ### Claim 10 (depends on 9) The method of claim 9, further comprising the step of filtering wavelengths captured by the SWIR detector with a filter disposed within the SWIR detector to isolate or remove predetermined wavelengths of light associated with the allergy skin testing area. ### Claim 11 (depends on 9) The method of claim 9, further comprising the step of transmitting the image captured by the SWIR detector to an electronic medical file. ### Claim 12 An allergy skin test reading system, comprising: an allergy skin test reading device including (i) a short wave infrared (SWIR) detector including a lens configured to enable the SWIR detector to capture an image of an allergy skin testing area of a patient, wherein the SWIR detector is an indium gallium arsenide (InGaAs) detector configured to detect wavelengths between (a) 1,350 nm and 1,450 nm, and (b) 1,600 nm and 1,800 nm, to detect a wheal formed on the allergy skin testing area of the patient in response to an allergen introduced to the allergy skin testing area; a supporting structure configured to mount the InGaAs detector over the allergy skin testing area of the patient; an illumination device mounted to the supporting structure and configured to illuminate at least a portion of the allergy skin testing area of the patient; and a graphical user interface configured to display the image captured by the InGaAs detector. ### Claim 13 (depends on 12) The allergy skin test reading system of claim 12, wherein the SWIR detector is configured to detect the wheal formed on the allergy skin testing area of the patient during an allergen test. ### Claim 14 (depends on 12) The allergy skin test reading system of claim 12, wherein the SWIR detector comprises a filter configured to isolate or remove predetermined wavelengths of light associated with the allergy skin testing area. ### Claim 15 (depends on 14) The allergy skin test reading system of claim 14, wherein the filter is a bandpass filter that is configured to obscure veins in the allergy skin testing area to enhance detection and visibility of the wheal formed on the allergy skin testing area of the patient. ### Claim 16 (depends on 12) The allergy skin test reading system of claim 12, wherein the allergy skin test reading device further comprises a visual wavelength detector including a lens configured to enable the visual wavelength detector to capture an image of the allergy skin testing area of the patient. ### Claim 17 (depends on 12) The allergy skin test reading system of claim 12, wherein the allergy skin test reading device further comprises a processing device configured to analyze the wheal in the captured image of the allergy skin testing area of the patient and output a dimension associated with the wheal. ### Claim 18 (depends on 17) The allergy skin test reading system of claim 17, wherein the dimension associated with the wheal is a wheal diameter. ### Claim 19 (depends on 12) The allergy skin test reading system of claim 12, wherein the allergy skin test reading device further comprises a graphical user interface configured to display the captured image of the allergy skin testing area of the patient with the wheal.
