Description of intervention(s) / exposure
Participants will be asked to come in to a collection centre. They may be asked to fast for a minimum 12-hour fast in the morning. Participants may be be recontacted by our team, and would undergo the same procedures (venous blood collection, capillary blood collection, urine collection and/or saliva collection), not less than 6 weeks before the previous collection. A single session will last up to 60 minutes.

The Clinical Nurse will explain the study procedures (as per Information Sheet) and will obtain written informed consent.

Study procedures and data collection will include:

i) Medical history questionnaire: a code will be assigned to each participant. The Clinical Research Nurse will complete a brief medical history questionnaire, including date of birth, gender, past/previous medical history, and past/previous use of medications.
ii) Fasting: Participants may be advised not to consume food, alcohol or caffeine for 12 hours prior to the collection. They will also be advised that they can consume water during the fasting period. Prior to collection, participants will be asked to confirm when they last ate or consumed alcohol or caffeine: no risks associated.
iii) Venous blood collection: Venous blood will be collected from an arm vein by the Clinical Research Nurse following standard sterile techniques. The maximum amount of blood that will be collected will be about 50 ml (approximately 1/10 of a blood donation), drawn into appropriate tubes for analysis. The tubes with blood will be kept on ice for transportation to the pathology lab. Minimal physical risks associated with drawing venous blood are pain, bruising or bleeding at the time the needle is inserted. Serious adverse effects are blood clot or infection, but they are very rare. Some subjects may faint during the procedure. Those risks will be minimised by using careful sterile techniques, with the patients sitting comfortably on a chair. If bruising occurs, ice cubes or cold packs will be placed over the area for a few seconds, followed by the placement of a cotton pad and bandage over the site. If fainting occurs, needle will be removed and the participant will lie down and/or raise the feet for a minute or two. After resting for five to ten minutes, if the participant is feeling well and vital signs are normal, the participant can continue on as normal.
iv) Capillary blood collection: Capillary blood will be collected from a finger prick by the participant under the guidance of the Clinical Research Nurse following standard sterile techniques. The maximum amount of blood that will be collected will be 40ul (0.04ml) in 8 blood spots on purpose specific cellulose filter paper. The filter paper will be placed into a breathable envelope for transportation to the pathology lab. The blood spots will dry during transportation. Minimal physical risks associated with collecting capillary blood are minor pain, bruising or bleeding at the time the finger is lanced. A serious adverse effect could be infection, but this is very rare. Those risks will be minimised by using careful sterile techniques, with the patients sitting comfortably on a chair. A sterile safety lancet will be used to prick the finger.

After venous blood collection, capillary blood samples will be collected by the participant onto the filter paper, as per instructions provided at the collection.

v)Saliva and urine collection: Participants will be guided to self-collect saliva samples. Approximately 2 ml of saliva will be collected per test into a 2ml tube/saliva collection device using the passive drool method or using a saliva oral swab. Participants will be given a sterile, leakproof urine collection container, and instructed to collect up to 50 ml of urine from midstream, in a bathroom.
Venous blood samples, urine and/or saliva will be transported to the pathology lab at the end of each morning by the Research Nurse. Dried blood spot samples collected onto the filter papers will be provided to the Pathology Lab.

Samples will be analysed in duplicates.

Statistical methods / analysis
This study will compare data from samples taken by alternative methods to those of standard pathology methods. Data will be obtained from >100 participants for each test. Linear regression and Bland Altman analysis will be used to compare data. We will use non-parametric tests, ANOVA and Student’s t-test on paired measures
