Period / Round

I am going to explain you about Period/Round in clinical Study/Clinical Research here....

For example you got a clinical Study/Clinical Research trial with 2 Periods(There may be 3 or 4 too) of 24hrs (it may be 48,72 or 5 days/10 days or 20 days or a month and payment will vary with that) and 2 Ambulatory Samples/Blood Samples(There may be any number of samples or no samples).

Hours (hrs) are counted from dosing time but you have to stay in lab from checkin as lots of paperwork has to be done and also to refrain you from tea/coffee/smoking/drinking etc for at least 24hrs before dosing.

Study Details will be provided like this-


Total Payment Rs.11000

Period/Round -1
12 June - Check In
13 June - Dosing
14 June - Check Out
15 June - Ambulatory/Blood Sample(48hrs)(it may be 36hrs,48hrs,72hrs and so on)
16 June - Ambulatory/Blood Sample(72hrs)

Partial Payment on 16 June may be Rs. 500 to 5000. Also some amount in cash in given at each checkout by all labs.


Here it is 8 Days Gap but It may be any number of days gap. 
Note : washout period is difference in days from dosing to next dosing while gap is counted from checkout/last sample to next checkin.

Period/Round -2
25 June - Check In
26June - Dosing
27 June - Check Out
28 June - Ambulatory/Blood Sample(48hrs)
29 June - Ambulatory/Blood Sample(72hrs)
29 June - Safety/Post-Study Sample
29 June - Final Payment


Full remaining payment on 29th June.

Most of the lab pay full remaining amount on the day they take Safety/Post-Study sample at last period Checkout/Last Ambulatory Sample but few labs pay final amount after 1-2 days of Safety Sample.

In each period there is health checkup before check-in but you can visit the lab for check-in in afternoon or evening from 2nd period onward. For 1st check-in you need to visit the lab in morning or early morning.

Few labs may do alcohol test before Ambulatory sample so you must refrain from alcohol before check-in and ambulatory sample.

All timings for sample and checkout etc. are given from dosing time. So if there is an ambulatory sample at 84hrs, then 84hrs. are counted from your dosing time.
