1) Fasting sugar:

Fasting is required for 6-8 hours

2) Sugar after eating two hours:

The two hours are calculated from the beginning of eating (to start secreting insulin with the beginning of eating) and it is required to finish eating within 10 minutes at most.

If the patient is taking diabetes medication, the medication is taken unless there are special instructions from the attending physician.

Only water can be drunk during the two hours. (It is required to come to the lab five minutes before the two hours)

3) Blood sugar curve:

The patient is asked to take 150 grams of carbohydrates for 3 consecutive days before performing the test.

Fasting from 6 to 8 hours.

It is preferable to do the test between 7 and 9 in the morning. It is not allowed to eat or drink any food or drink during the test, only drink water and refrain from smoking.

Record whether the patient is pregnant or not. Due to the difference in the sugar dose with the normal patient.

Record taking diabetes medication and whether the medication was taken on the day of the test.

Recording the type of oral medication or insulin.

A fasting blood sugar (FBG) sample is taken. Then the patient is given a dose of sugar dissolved in: 250 to 300 ml of water. Then the rest of the samples are taken

4) Blood fats:

Fasting is required for 11 to 14 hours (to complete the absorption of the previously eaten fats and stabilize their percentage in the blood). Drinking water is allowed.

5) Farm urine:

It is required to wash the hand and genitals with water and soap and disinfect the urinary opening with an antiseptic (Dettol), then wash again with water to remove excess antiseptic, then empty the first drops of urine into the toilet and put the rest in the sterile container provided by the laboratory.

In case the sample is sent from home, it must reach the laboratory within two hours at most (so that the microbe does not die or the bacterial count increases).

Do not take antibiotics for 48 hours.

Use the first urine in the morning.

Use the middle of the urethra.

For long-term catheter users, it is not taken from the urine collection bag.

For infants, a urine collection device is taken from the laboratory, specifically for this age group.

6) Urine for 3 consecutive days or spit for 3 consecutive days:

This test is used to detect tuberculosis in 3 samples because the microbe may appear in one sample and not in another.

7) 24-hour urine collection:

The patient empties the bladder completely in the toilet and records the time at that time, then collects any urine after that in a designated collection container received from the laboratory. Urine collection continues until the same time at which the collection began the next day, and the urine is stored in the refrigerator until it is sent to the laboratory.

Please note that some tests require obtaining a preservative from the laboratory to collect on.

8) In case of calculating microalbumin in urine:

Collect 24 hours of urine and empty the urine collected in the bladder in the morning after waking up from sleep, then drink water and continue to rest until the collection is completed without making any effort

9) VMA -5HIAA - Catecholamine analysis:

It is required to collect 24 hours of urine in a special bottle that the patient receives from the laboratory, and it is required that the patient refrain for 48 hours from eating nuts - tea - coffee - chocolate - vanilla - plums - pineapple - eggplant - tomatoes - bananas - biscuits - cake - cakes.

10) Creatinine extraction (creatinine filtration):

The patient's weight and height must be taken, as well as the number of 24-hour urine volume bottles

A blood sample must be drawn from the patient to perform the analysis in addition to collecting 24-hour urine.

11) Stool analysis:

Not in diapers or absorbent materials for fluids or unclean containers - avoid mineral oils, bismuth, magnesium.

Wait 1 week after taking barium or laxative

12) Stool culture:

The sample must reach the lab within 2 hours at most (because there are some microbes that die quickly).

Samples in diapers or cardboard boxes are not accepted because they absorb fluids from the sample and dryness kills microbes.

Refrain from antibiotics for 72 hours.

13) Stool analysis for occult blood:

The patient abstains for 48 hours from eating all types of red meat, liver, radishes, rheumatism medications, or medications containing aspirin, vitamin C, cortisone, or iron, and laxatives are not allowed.

14) Asthma and epilepsy medications:

A sample is taken before the morning dose to calculate the drug level at the lowest level (low), then another sample is taken several hours after taking the medication (it varies from one medication to another according to the doctor's instructions) to calculate the highest drug level in the blood (peak) (so that we can make sure that the dose the patient is taking is the effective dose without reaching drug poisoning).

It is required not to vomit or have diarrhea for 48 hours before the test because this will affect the dose and thus the drug level in the blood.

The medication is taken for 5 days regularly in order to reach a stable level in the blood.

15) Thyroid analysis:

Write the name of the medication the patient is taking Eltroxin - Neomercazole - Euthyrox Iodine.

Was the gland removed?

16) PTT -PT fluidity analysis:

Is the patient taking a blood thinner such as (Marevan - Coumadin - Heparin - Vitamin K) and what is the dose? When did the treatment start? And did he stop treatment at any time? Did he take any other treatment with the medication (aspirin - rheumatism medications)?

Is there any bleeding from the gums, under the skin, or from the nose?

In children, what is the reason for the analysis (before surgery or is there bleeding)?

17) Platelet function tests:

Fasting for 10 hours. Stopping aspirin, anti-inflammatory drugs, and anticoagulants

18) G6PD -FAVISM anemia tests:

It is required that the analysis not be performed after a blood transfusion or relapse until after 3 months.

1) Semen analysis:

It is required to abstain from sexual intercourse or wet dreams for 4 consecutive days (so that the quantity is not affected)

It is preferable to give the sample in the laboratory, taking care to put the entire sample, including the first drops of semen, in the special bottle (because these drops contain 3/4 of the number of sperm).

If you bring the sample, someone will record the time of bringing the sample and will not accept a sample from home that has been in it for more than 30 minutes.

It should be noted that the presence of water, soap or cream inside the semen bottle affects the movement and vitality of the sperm.

2) Prostate:

At a previous appointment, it is required to abstain from sexual intercourse for 4 days before the analysis and to hold urine for an hour before the test in order to take a urine sample before massaging the prostate and another urine sample after massaging the prostate (to differentiate whether the pus is from the urethra or the prostate).

3) PSA analysis:

Prostate tumor indications: The patient should refrain from inserting an endoscope or catheter 10 days before the test because this will affect the test result (unless the attending physician has another opinion).

4) Penile swab:

Retain urine inside the bladder for an hour before the test (so that the urethra is completely dry to ensure that the microbe is from the penis and not from the urine).

5) Gynecological swab:

This sample is by appointment and it is required not to have intercourse for two days (to ensure that the microbe is from the uterus and not from the semen).

Do not wash the vagina on the day of the test (to give the microbe a chance to grow while abstaining from antibiotics for 48 hours).

General tumor indications for the digestive system 19.9 CA::

It is preferable to fast for 6-8 hours because (food irritates the membranes lining the digestive system).
