Lab Chemist

☛ knowledge of chemistry

☛ chemistry or chemical engineering degree

☛ communication

☛ attention to detail

Responsibilities of clinical lab technician varies with the department you are assigned to, but usually it involves

☛ Wide range of testing

☛ Running complex analysis

☛ Examine blood cells with mircoscope

☛ Scanning of specimen

☛ Using expensive chemicals wisely

☛ Maintaining and monitoring various equipment’s

☛ Checking contamination in chemicals at regular interval

Different techniques used for placing samples under micro-scope are

☛ Dry Mount: You simply put section of specimen with a cover slip over a sample

☛ Wet Mount: Samples are placed under various liquid medium like glycerine, water, brine and water

☛ Smear Slides: In this technique, sample is smear over the slide and on top it another slide is placed without forming bubbles

☛ Squash Slides: In this technique, lens tissue is used over the wet mount, and it will remove excess water

☛ Staining: Stains such as iodine, methylene blue and crystal violet is used to stain the specimen

To avoid an imbalance in centrifuge it requires

☛ Balanced loading of the centrifuge rotor

☛ Even number of tubes should be loaded facing each other or in the opposite direction

☛ When odd number of tubes are loaded make sure, you make it even with adding one more tube with an equal amount of water of that of the sample tube

This question can be tricky because you need to show your worth without sounding cocky or arrogant. Research the business ahead of time and become familiar with its mission and values. Take the time to figure out how your personal qualities fit the needs of the business and use that fit to provide your answer.

Even if you are a fresh graduate, you likely have some experience as an extern. Prepare for this question in advance by thinking of all procedures in which you have assisted. When answering the question, give a detailed but succinct account of your experience and your contribution to the experience.

There was a time when a lab process that I had performed did not produce the results that the physician expected. I was asked to find out if there had been any inconsistencies. I performed the result again with the same results. In trying to determine what had happened, I discovered that the lab technician who had taken the sample had mixed up the labels.

Blank term is used to refer the sample tube which does not contain the analyte.

The most common methods of sterilization practised in lab are

☛ Dry heat: Specimen containing bacteria is exposed to high temperature

☛ Wet heat: Pressurised steam is used to kill microbes, for example, autoclave that is like pressure cooker that produces steam.

☛ Filtration: Filtration is used where filters are as small as 0.2um is used

☛ Radiation: UV has limited penetration, so it is generally safe to use although it is less effective to X-rays and gamma rays. X-rays and gamma rays are used only for special purposes only

☛ Solvent: Solvent like ethanol and iso-propanol kills microbial cells but not the spores

☛ exposure to toxic/poisonous materials (not healthy for the workers)

☛ boring routine, doing same thing over and over, monotonous

☛ quality control: testing samples of raw materials or products either in mid-stage or close to final stage to make sure that they are of high enough quality, reaching the standards and qualifications, before the product can be mass produced

☛ research and development of products

☛ perform various chemical methods and procedures in the lab

☛ the chemistry knowledge you get to apply

☛ the technology

☛ Failure to pre-wet the pipette tip

☛ Disregarding temperature – temperature equilibrated

☛ Tip wiping over and again

☛ Choosing wrong pipetting mode

☛ Working too quickly

☛ Pipetting at a wrong angle

☛ Using wrong pipette tips

☛ nderstanding all the chemistry, following the manufacturing/production rules and standards

☛ when something is wrong with the raw materials:

☛ if sample is not good, call the raw material manufacturing company, and send back the materials

☛ when something is wrong with the final products:

☛ if sample is not good, keep hold of product and find out the problem by contacting the different departments

☛ solving the problem is hard; meeting with different departments to solve the problem

☛ tracing back to the processing stages of product

Gas sterilization depends on factors like

☛ Concentration of the gas

☛ Humidity

☛ Time of exposure

☛ Temperature

☛ Nature of the load

☛ during the "high season" (summertime; higher demand) : overtime --> 10 hours or more

☛ regular season: 8 hrs

☛ during "slow season" : 8 hrs

☛ Following GLP standard, minimizes the chance of error occurs due to humans

☛ It supports for product registration, and also assures the suitability of data to the regulatory authorities

☛ It helps to reduce the cost of industry and governments by avoiding duplicative testing

☛ It helps to re-create a study from the recorded data and information

Material Safety Data Sheets are used to handle chemical use in a laboratory. They are issued with every chemical that any lab uses or stocks.

Be very honest and clear with your answer. If you have past experience on the job, state the number of years you have worked. If you are a recent graduate, detail how long you served in an externship as well as any relevant volunteer experience you have. Explain how you have interacted with patients and make sure to emphasize that you are completely comfortable working with patients of all ages and backgrounds.
