Your health should be kept under control and the ideal is a blood test once a year. This is only feasible if it is not necessary to control any parameter in particular as cholesterol or blood sugar. As one does not do tests every day, we must take into account certain precautions, so that the results are accurate and with quality.

Some analyses should be done on an empty stomach so that the food eaten does not affect the results. If you are asked to come fasting to harvest, try taking the last meal 12 hours before. If you are taking any medication on an empty stomach, ie diabetic, ask your health care provider, how to proceed.

Analyses to be carried out during pregnancy do not require fasting except Glucose Evidence or the first determined glycemia in pregnancy.

In the case of infants and children check with your pediatrician or with the laboratory of the procedure.
Avoid physical exertion during the 2 hours prior to a crop and try to be calm, because stress alters the concentration of some parameters. You should also avoid coffee and alcohol within 4 hours prior to harvesting.

There are some analyses that require advance preparation, see the Package Insert for Harvests, or the Lab to learn about the care to take before you make them, as well as the appropriate way to collect the sample.

The collection of some samples such as urine, feces must be carried out in suitable containers, so as to have the certainty that these containers were not subjected to any specific treatment or additives, which could alter the results of analyses.



ROUTINE (cholesterol, triglycerides, glucose, etc)

Keep fasting for 10 to 12 hours taking the last meal about 20 hours the day prior to blood collection. This is extremely important in the case of lipids-fats (Cholesterol, HDL, Triglycerides, Lipid profile, total lipids and phospholipids). Does not apply in cases of being a baby or child and if you are diabetic, consult your doctor about fasting to apply.

Avoid physical exertion during the 2 hours prior to harvesting. Do not smoke 1 hour before harvest.
Do not drink alcohol, coffee or tea within 4 hours prior to harvesting.

Try to harvest from 08:00 to 11:00 (the reference values were calculated in this range and there are variations throughout the day).

Try to be calm before the harvest, because stress alters the concentration of some parameters to be measured.


No need for diet. Do not drink alcohol.

If you take medication like Aspirin, anti-inflammatories and corticoids you must stop taking them 2 days before the test. You must collect a small amount of feces (half a size walnut) for a container supplied by the laboratory.

The delivery to the laboratory must be made on the day of harvest.


It is important that the sperm is harvested in good personal hygiene conditions. Before harvest you must take a shower washing the penis with soap and water.

We suggest that you have a period of 3 to 5 days of sexual abstinence prior to harvesting. The sperm must be collected in sterile collector.

After harvesting, the sperm must be delivered to the laboratory as soon as possible (within 30 minutes), and maintained as much as possible at body temperature.
