Abstract

A method is provided for receiving and handling a plurality of clinical samples and managing information associated therewith for generating and reporting any of a plurality of different diagnostic results from each sample in a timely manner, particularly within about thirty (30) hours. Methods described comprise, for example, receiving a plurality of single gynecological swab samples, each having identity and test requisition information associated therewith, wherein the test requisition information indicates a test for at least one causative agent, from a choice of a plurality of agents (for example, between about 5 and about 25 different microbiological agents) and managing information associated therewith for generating and reporting any of a plurality of different diagnostic results for each sample.

Claims

1. A method of handling a plurality of clinical samples and managing information associated therewith for reporting a sum of diagnostic results for each sample comprising:

receiving a plurality of samples, each having identity and test requisition information associated therewith wherein the test requisition information indicates a test for at least one causative agent from a plurality of agents listed,

entering the information into a system to create a requisition file for each sample,

processing the information to create a list of samples to be tested for each causative agent,

dispensing an aliquot corresponding to each sample, each into an individual vessel, to create a secondary sample for each designated test,

assembling a general supply of master reagent mix for each test for each different causative agent,

combining an aliquot of master reagent mix for each test with each corresponding secondary sample to produce a diagnostic test reaction for each secondary sample,

incubating each reaction,

determining the presence or absence of a certain product of each reaction to produce a result,

recording the result of each reaction,

combining the result of each reaction derived from each primary sample into the requisition file for each sample on the system, thereby producing a sum of results for each sample, and

reporting the results,

wherein at least one agent of the plurality of agents listed is selected from the group consisting of Molluscum contagiosum Virus, Mycoplasma genitalium, Mycoplasma hominis, Candida dubliniensis, Candida krusei, Candida lusitaneae, Atopobium vaginae, erythromycin-resistant Streptococcus agalactiae, clindamycin-resistant Streptococcus agalactiae, Lymphogranuloma venereum, HPV-16, HPV-18, HPV-31, HPV-33, HPV-35, HPV-39, HPV-45, HPV-51, HPV-52, HPV-56, HPV-58, HPV-59, HPV-66, HPV-68, HPV-6/11, HPV-42, HPV-43, and HPV-44.

2. The method according to claim 1 wherein clinical samples are gynecological swabs.

3. The method according to claim 2 wherein at least three (3) agents of the plurality of agents are selected from the group consisting of Bacteroides fragilis, Candida albicans, Candida glabrata, Candida parapsilosis, Candida tropicalis, Chlamydia trachomatis, Gardnerella vaginalis, Haemophilis ducreyi, Herpes simplex virus subtype 1 (HSV1), Herpes simplex virus subtype 2 (HSV2), Human papillomavirus (HPV), Mobiluncus mulieris, Mobiluncus curtisii, Molluscum contagiosum Virus, Mycoplasma genitalium, Mycoplasma hominis, Neisseria gonorrhoeae, Treponemapallidum, Trichomonas vaginalis, Ureaplasma urealyticum, and Streptococcus agalactiae (Group B Streptococcus).

4. The method according to claim 3 wherein at least four (4) agents of the plurality of agents are selected from the group.

5. The method according to claim 4 wherein at least five (5) agents of the plurality of agents are selected from the group.

6. The method according to claim 2 wherein the plurality of agents comprise Chlamydia trachomatis and Neisseria gonorrhoeae.

7. The method according to claim 4 wherein the plurality of agents comprise Gardnerella vaginalis, Mobiluncus mulieris, Mobiluncus curtisii, and Bacteroides fragilis.

8. The method according to claim 4 wherein the plurality of agents comprise Candida albicans, Candida glabrata, Candida parapsilosis, and Candida tropicalis.

9. The method according to claim 3 wherein the plurality of agents comprise Mycoplasma genitalium, Mycoplasma hominis, and Ureaplasma urealyticum.

10. The method according to claim 3 wherein the plurality of agents comprise Herpes simplex virus, Treponema pallidum, and Haemophilis ducreyi.

11. The method according to claim 2 wherein at least one (1) agent of the plurality of agents is selected from the group consisting of Gardnerella vaginalis, Molluscum contagiosum Virus, Mycoplasma genitalium, and Mycoplasma hominis.

12. A method of receiving and handling a plurality of clinical samples and managing information associated therewith for reporting any of a plurality of different diagnostic results for each sample comprising:

receiving a plurality of single samples, each having identity and test requisition information associated therewith wherein the test requisition information indicates a test for at least one causative agent from a plurality of listed agents,

entering the information into a system to create a requisition file for each sample,

extracting nucleic acid from each sample,

preparing the nucleic acid from each sample to provide a standardized primary nucleic acid solution corresponding to each sample,

processing the information in the system to designate a test on each nucleic acid for at least one causative agent,

dispensing an aliquot of the primary solution from each sample into an individual vessel to create a standardized secondary nucleic acid sample for each designated test,

assembling a general supply of master reagent mix for each test for a different causative agent,

combining an aliquot of each master reagent mix with each corresponding secondary nucleic acid sample for each test to produce a diagnostic test reaction for each secondary sample,

incubating each reaction,

determining the presence or absence of a certain product of each reaction to produce a result,

recording the result of each reaction by means of the system,

combining the result of each reaction derived from each primary solution into the requisition file for each sample on the system, thereby identifying at least one causative agent in each sample, and

reporting the results,

wherein at least one agent of the plurality of listed agents is selected from the group consisting of Molluscum contagiosum Virus, Mycoplasma genitalium, Mycoplasma hominis, Candida dubliniensis, Candida krusei, Candida lusitaneae, Atopobium vaginae, erythromycin-resistant Streptococcus agalactiae, clindamycin-resistant Streptococcus agalactiae, Lymphogranuloma venereum, HPV-16, HPV-18, HPV-31, HPV-33, HPV-35, HPV-39, HPV45, HPV-51, HPV-52, HPV-56, HPV-58, HPV-59, HPV-66, HPV-68, HPV-6/11, HPV-42, HPV-43, and HPV44.
