Pass 7 blood video
The tests will be ordered by the GP (General Practice), the blood sample will be taken by
the nurse, placed in a temperature-controlled bag, and couriered to the lab. The sample
will be entered into a computer log by the receptionist as it enters the lab so it can be
tracked throughout the system. The sample will then be placed in a centrifuge by the
biomedical support team, where it will be spun at extremely high speeds, causing the
blood plasma to separate from the blood. As a result, the necessary test can measure
substances like ferratin in the plasma. To obtain the results, the biomedical scientist put
the sample into an analyser. If the result is normal, it will simply be returned to the
doctor, but if it is abnormal, it will be flagged for further investigation by a biological
scientist. The abnormal results will then be returned to the doctor along with the
biomedical scientist's notes. Each sample will be manually examined by the advanced
biomedical support staff member to make sure no mistakes were made by the
equipment or other personnel participating in the procedure. The biomedical support
staff member then re-inserts them into the analyser for a second check to rule out any
potential faults, The sample will then be placed in a cool chamber, which will be kept at 4
degrees Celsius, where it will be kept for 5-7 days in case any problems occur. If the
doctor orders any more tests, the sample may need to be retested. To avoid any
contamination and to protect any personal data, the quality manager and health and
safety adviser make sure the samples are put into yellow disposable bins and that they
are burned at the end of the process. The patient's NHS number is used to identify all
results in the computer database. Approximately 8000–9000 samples are run through
the labs each day.
Pass 8 impact fluids
Mid-pallet and mid-batch production samples will be gathered, and they will be
forwarded to Impact Fluids by FedEx or the mail. Numerous samples of new products will
be used to evaluate the quality and any potential production variances. There will only
be a mid-pallet sample for regular goods.
The receptionist will physically copy and book the sample. They document:
the moment the sample was obtained
that of the work order
serial number
Container number
and how the bags are packaged. It might be packaged in bags, pales or large
bags.
This establishes a record of the sample's creation and ensures the product's traceability.
Additionally, the receptionist logs each sample's COSHH evaluation in the book. A
COSHH assessment is required for every new product, and they are done by chemical
group. In terms of the chemical type they could produce, they examine whether it is
similar to other products or if it differs in any way. The COSHH safety document must be
revised if the new product uses new raw materials or calls for new manufacturing
processes or tests. The company must make sure that the safety data sheets comply
with UK law because samples are obtained from all over the world. Based on the nature
of the product, the sample is also given a letter code for the business's system (local
code). The receptionist will record the full product name and the number of samples
from each batch. Then, to ensure that there is a physical and digital copy of the data, all
of this information is likewise stored digitally on the computer. This ensures information
security and traceability.
, The sample is sent to the lab technician when it has been scheduled. Customers submit
computer-based requests for technical support to the company's managers, who then
delegate duties to the lab technicians. Reformulating one of the business's products is a
typical test that is asked. A customer has asked for a mud test at this location. The
technician will create a specification for the mud's exact formulation and ensure that it
satisfies the clients' needs.
Each lab technician has a lab book with numbered pages that is uniquely theirs. The lab
technician writes down the service request's title, the date, and a few phrases describing
the tasks they will perform. The lab technician will record all data gathered as they work
in the lab in the lab book. Using the lab book is crucial because it enables the lab
technician to record information right away as the tests are completed, reducing the
likelihood that they will forget something. A lab book is portable, but a computer is not
practical in all of the lab spaces. The lab book adds an added layer of protection because
it ensures that the data, which will also be kept digitally, has a physical backup in case of
data loss, corruption, or virus attacks. The lab book also guarantees traceability because
each lab technician has their own book, ensuring that all work is tracked and kept in a
single location.
The lab technician writes down the date, the project's title, and a few comments about it
in the lab book. There is no need to document every step of every test because every lab
technician is required to adhere to the standard operating procedures. These methods
are covered in company training for employees, who also have a red, amber, and green
system. The lab technician is on "green" right away following training. They shift to "red"
and require supervision or retraining on that technique in order to maintain competency
if they don't conduct a procedure for three years. This guarantees the work's precision
and safety. In the case of rheology, the lab technician would record the temperature and
type of rheometer used, but not the complete procedure. The lab tech does record the
test guidelines, but not the method.
The lab technician fills out the lab book with information such as a rheology table and
the formula for the mud under test. Formulation is the combining of ingredients. To
maintain traceability, all raw materials have batch numbers and booking in numbers. A
database on the computer will also have all the information, including the booking
number, what it is, where it came from, and when it was received. The lab technician
records the temperature and the tests they will run, in this case, rheology, in the lab
book.
The sample is subsequently subjected to rheology by the lab technician. They keep track
of the test, the apparatus used, and the rheology temperature. They use a table
rheometer to obtain measurements at various speeds. They keep track of the value the
rheometer displays for each speed. For data sets, the lab technician occasionally needs
to repeat tests, but not for rheology because they would always receive the same
outcome.
