Biological sample collectors and handling thereof
Disclosed is a biological sample collector 500 comprising a solid support 12 having plural discrete areas ( 22, 24, 26, 28 FIG. 1 ) for accepting a biological sample, each area being chemically differentiated, for example by having a different chemical treatment sorbed onto the solid support. An envelope 530 encloses the solid support. A cover portion 520 can cover the biological sample after collection to prevent infection. UV light can be applied to the collected sample to reduce the risk of infection.
1. A biological sample handling method comprising the steps of:
a) providing a sample collector comprising a solid support, the solid support having plural chemically differentiated sample receiving areas;
b) applying a biological sample comprising RNA or DNA of an infectious virus and of a host to one or more of said areas;
c) exposing said one or more areas to UV light sufficient to substantially inactivate the infectious virus present in the biological sample; and
d) following step c) determining the RNA or DNA content of the infectious virus and the host in the biological sample.
2. The sample handling method of claim 1 , further comprising the steps of:
e) excising a portion of one or more said sample receiving areas into a receiving vessel; and
f) performing an assay on biological material derived from the excised portion without transferring said excised portion to another vessel.
3. The sample handling method of claim 2 , wherein said assay includes protein identification and/or enzyme identification, in each case of either biological sample material relating to the host or relating to the infectious virus to be identified within the sample.
4. The sample handling method of claim 1 , further comprising the steps:
a) drying said applied sample;
b) covering said dried areas with a cover flap, optionally held in place by means of pressure sensitive adhesive; and
c) storing said sample collector.
5. The sample handing method of claim 4 , wherein the cover flap allows UV light substantially to pass therethrough.
6. The method of claim 1 , further comprising collecting the infectious virus after the step (d).
7. The method of claim 6 , wherein said infectious virus is viral RNA.
8. The sampling handling method of claim 1 , wherein the RNA or DNA is from Ebola Virus Disease, Human Immunodeficiency Virus, or Influenza Virus.
9. The sample handling method as claimed in claim 1 , wherein one or more of the sample receiving areas are coated with an antioxidant to protect the biological sample from degradation by UV light.
