It usually means whomever was performing the lumbar puncture or "spinal tap" missed the sub-dural space where the spinal fluid is located. It may also be that the patient was dehydrated or was leaking CSF (cerebral-spinal fluid) thus making it very difficult to obtain a sample.

What is the use of graduate cylinder?
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 mL, 25 mL, 50 mL, or 100 mL and up to as large as 1 or 2 liters.

What does it mean to have your blood test for pregnancy come back Indeterminate?
It means that you don't have enough hCG in your blood yet to be considered pregnant, but you also have too much for them to give you the 'not pregnant' sign.
You might have an ectopic pregnancy or an early pregnancy, but not always, so try not to stress too much about it, as hard as it can be. (I am going through this right now.)
Doctors have different cut offs for what is 'pregnant' vs. 'indeterminate' vs 'negative', so you could ask for a number, if the test was quantitative (many tests now are).
Why is there a need for us to shake the clinical thermometer prior to each use?
If the clinical thermometer is a mercury based thermometer, it needs to be shaken down prior to each use. This is because there is a pinch point between the mercury reservoir bulb and the capillary tube, to ensure that the mercury does not shrink back into the bulb after the temperature has been taken. The mercury has therefore to be shaken back into the bulb before another measurement can be made.
One should note that in many countries use of mercury based clinical thermometers is now discouraged (because mercury is toxic) and electronic thermometers are used in stead - these do not need shaking.
What does a high potassium level indicate?
A high potassium level is an indication of hyperkalemia. This is dangerous as it may lead to changes in heart rhythm or even death.
What does after deductible mean?
"After deductible" means you will not get coverage or certain benefits until a deductible has been met. Insurance policies often have more than one deductible. For example, you may have a $1,000 per year deductible for certain medical expenses, and another deductible for prescription drugs. If your prescription drug deductible is $500 per year, you will have to pay out of pocket the first $500 of drug cots before your plan will kick. Many plans have complicated formulas for how deductibles are applied and how they are met so there is no one answer. But "after deductible" always means that the person with the insurance policy will have to pay something first, before getting reduced-cost, free, or co-pay services and drugs.
