Background
Currently, more and more products that can realize on-site sampling and can immediately obtain the detection result are researched and applied to clinics, and the detection is generally called point-of-care testing (POCT). For example, Lateral Flow Test strips (late Flow Test strips) are currently commonly used in point-of-care products.

The reaction membrane is generally provided with a detection line 41 and a control line 42, the control line may be upstream or downstream of the detection line, or some detection test strips may not be provided with the control line. And the signal of the detection line on the reaction membrane is linearly related to the content of the analyte in the sample to be detected, so that whether the analyte exists in the sample or the concentration of the analyte is judged. The lateral cross flow test paper can be assembled in a test board consisting of an upper cover plate and a lower cover plate, and the water absorption pad is not exposed to the external environment. The test strip 101 may also be in the form of a strip as shown in FIG. 2, with a sticker 6 attached to the sample pad and the labeled conjugate releasing pad of the test strip.
The solution to be tested can be added to the sample pad of the test strip by dropping, or the lateral flow test strip 101 can be inserted into the small tube containing the solution to be tested by dipping the sample pad in the solution to be tested as shown in fig. 3. The solution to be measured on the sample pad flows through the labeled conjugate releasing pad, the reaction membrane in order, and is finally absorbed by the water absorbing pad. When the test strip 101 in the form of a test strip is used, as shown in fig. 4, an operator needs to hold the absorbent pad and take out the test strip from the small tube to observe the test result or discard the test strip. If the solution to be tested contains infectious pathogenic viruses or bacteria, such as HBV, HCV, HIV, malaria, dengue fever, influenza, respiratory syndrome of the middle east, SARS, and the new crown antigen 2019-nCoV, etc., these pathogenic factors (viruses or bacteria, etc.) remain on the absorbent pad. Once the operator is not wearing gloves or otherwise performing undue manipulation, the fingers holding the pad may be exposed to these agents, which presents a significant risk of infection.

Furthermore, self-adhesive stickers are stuck on the sample processing pad and the water absorption pad.
Preferably, the self-adhesive sticker is provided with a hand-pinching area indicating mark corresponding to the hydrophobic element.
Furthermore, a detection line and a control line are arranged on the reaction membrane.

Further, the sample processing pad includes a sample pad and a labeled conjugate releasing pad which are stacked on each other from upstream to downstream.
Furthermore, a layer of self-adhesive sticker is pasted on the upper surfaces of the sample processing pad and the water absorption pad.
The utility model has the beneficial effects that: the hydrophobic element is arranged at the front end of the detection test paper and can be used as a holding area to prevent the sample solution on the absorbent pad from flowing further to the area where the operator holds the detection test paper.

In a preferred embodiment, the hydrophobic element is preferably sized to allow the operator's finger to hold the test strip without touching the absorbent pad.
In contrast to fig. 1, the absorbent pad shown in fig. 5, 6, 7 has an upper edge 51 that is not aligned with the upper edge 11 of the support plate, but is at a distance therefrom. In a preferred embodiment, the specific value of the distance is suitable for the operator's finger to hold the test strip without touching the absorbent pad, so as to minimize the probability of touching the absorbent pad by the operator.
