- PSA, which stands for Prostate-Specific Aantigen, is a protein produced by the prostate gland. It is present in the blood of all men at low levels, but PSA levels often rise, sometimes dramatically, in the presence of prostate cancer.(Keith Brofsky/Photodisc/Getty Images).or men under 50, healthy PSA levels will usually range between .3 and 2.5 nanograms per milliliter (ng/mL), with an average of 1.2. In the presence of cancer, PSA levels can rise to up to 160 ng/mL. Jupiterimages/Goodshoot/Getty Images. Men From 50 to 60.

Overview Results of PSA tests are reported as nanograms of PSA per milliliter of blood (ng/mL). There's no specific cutoff point between a normal and abnormal PSA level. Your doctor might recommend a prostate biopsy based on results of your PSA test. Variations of the PSA test.

- He was not surprised by the rate of prostate cancer found by the analysis because a 1990 study of 5,250 autopsies found a prostate cancer prevalence of 15%-60% in men 60-90 years old, and PSA values of 4 ng/mL or less in 90% of them.

Medical Definition of PSA The “normal” PSA serum concentration ranges between 1.0 and 4.0 ng/mL. However, since the prostate gland generally increases in size and produces more PSA with increasing age, it is normal to have lower levels in young men and higher levels in older men.

- During a PSA test, a small amount of blood is drawn from the arm, and the level of PSA is measured: 1  Levels under 4 ng/mL are usually considered “normal.”. 2  Levels over 10 ng/mL are usually considered “high”. 3  Levels between 4 and 10 ng/mL are usually considered “intermediate.”.

Should I have a prostate biopsy? Statistically, the probability of having a prostate cancer present with a PSA of between 4 and 10 is around 22 per cent. Once the PSA level rises above 10, the probability goes up to the order of 64 per cent.

Learn how UpToDate can help you. In men with PSA levels between 2.5 ng per mL and 4.0 ng per mL, physicians should consider an individualized risk assessment that incorporates other risk factors for prostate cancer (e.g., black race, family history of prostate cancer, older age, abnormal digital rectal examination findings).

Free/total PSA ratio is a powerful predictor of future prostate cancer morbidity in men with initial PSA levels of 4.1 to 10.0 ng/mL. Biopsies were performed for those with PSA levels greater than 10.0 ng/mL or with a PSA velocity of 1.0 ng/mL or greater in consecutive screening. The follow-up period was 1 to 12 years, and the mean number of screenings was 3.8.

What is considered a normal range for PSA test? There is agreement that patients with a total PSA level greater than 10.0 ng/ml are at an increased risk for prostate cancer (more than a 67% chance, according to the ACS). Levels between 4.0 ng/ml and 10.0 ng/ml may indicate prostate cancer (about a 25% chance, according to the ACS), BPH, or prostatitis.est Answer: The normal value for total PSA has been set at less than 4.0 ng/ml (nanograms per milliliter of blood). There are some that feel that this level should be lowered to 2.5 ng/ml in order to detect more cases of prostate cancer.

PSA test About one in three men with a PSA level between 4 and 10 ng/ml will have prostate cancer, although this proportion varies with the population tested. Studies have shown that there is still a small risk of prostate cancer even if blood PSA levels are normal for age (a false negative result).

how long for psa marker to return to normal after UTI? Total PSA levels between 4.0 ng/ml and 10.0 ng/ml may indicate prostate cancer (about a 25% chance, according to the ACS), benign prostate hyperplasia (BPH), or inflammation of the prostate. These conditions are more common in the elderly, as is a general increase in PSA levels.

- However, this also depends on age. The age-specific upper limits of normal for Caucasians are shown in Table 1 (http://www.pccnc.org/early_detection/psa/). A PSA above these levels can trigger prostate biopsy as it may indicate PCa.

What is cea test normal range? It is important to note that a test that is positive for CEA may not always be indicative of cancers. It is due to this reason that this test is not used to screen for cancers. The CEA blood test normal range is from 0 to 2.5 micrograms per liter.In people who smoke regularly, this normal range is slightly increased. For them, the CEA blood test range is 0 to 5 micrograms per liter. Values slightly higher than this are accepted as normal.However, if the CEA values are considerably higher, further testing may be prescribed by the doctor to look for possible cancerous growths in the various parts of the body.t is important to note that a test that is positive for CEA may not always be indicative of cancers.

Learn how UpToDate can help you. Men ages 45 to 49. Men ages 45 to 49 should have a baseline PSA test. If the PSA level is 3 ng / mL or higher, men should talk with their doctor about having a biopsy of the prostate. If the PSA level is between 1 and 3 ng / mL, men should see their doctor for another PSA test every two to four years.

- Your “normal” PSA depends on your age, but even if your PSA level is elevated between 4 and 10, you have only about a 25 percent chance of prostate cancer. Here are some reasons, besides prostate cancer, that your PSA level could be above normal.

Drain (surgery) Negative pressure wound therapy : • Negative pressure wound therapy-Involves the use of enclosed foam and a suction device attached; this is one of the newer types of wound healing/drain devices which promotes faster tissue granulation, often used for large surgical/trauma/non-healing wounds.

- 1 Men with a PSA level below the age-specific limit of normal can have PCa. 2  Moreover, many men with a PSA level between the age-specific upper limit of normal and 10 ng/mL will not have PCa. 3  This is due to the fact that PSA is not cancer-specific and is produced by both cancerous and non-cancerous prostate cells.

Cancer 1 Seven of the 10 men with a higher than normal PSA level will be found not to have prostate cancer at the time of screening. 2  90 men out of 100 tested will have a normal PSA level. 3  Of these 90 men 4  : 88 of the men with a normal PSA level will not have prostate cancer.o test is right all the time, and this is true of the PSA test. For every 100 men over age 50, with no symptoms, who have the PSA test 1  : 10 men out of 100 tested will have a higher than normal level of PSA.

PSA PSA test results can be interpreted a number of different ways and there may be differences in cutoff values between different laboratories. The value for total PSA below which the presence of prostate cancer is considered to be unlikely is 4.0 ng/ml (nanograms per milliliter of blood).

- It is values between 4 and 10 ng/mL that are the most ambiguous; men in this range may benefit most from refinements in the PSA test. The risk of cancer based on PSA levels follows: PSA levels under 4 ng/mL: normal 4 to 10 ng/mL: 20 to 30% risk 10 to 20 ng/mL: 50 to 75% risk Above 20 ng/mL: 90%.ut only about 50% of men with a PSA velocity below 0.75 ng/mL per year have cancer. The test is used primarily to determine the need for a repeat biopsy in those with PSA levels between 4 to 10 ng/mL and a prior negative biopsy.

PSA 1 Total PSA levels between 4.0 ng/ml and 10.0 ng/ml may indicate prostate cancer (about a 25% chance, according to the ACS), benign prostate hyperplasia (BPH) , or inflammation of the prostate.2  These conditions are more common in the elderly, as is a general increase in PSA levels.f prostate cancer is diagnosed, the total PSA test may be used as a monitoring tool to help determine the effectiveness of treatment. It may also be ordered at regular intervals after treatment to detect recurrence of the cancer.

BPH Diagnosis The PSA level also is determined in part by the size and weight of the prostate. The test measures the amount of PSA in the blood in nanograms per milliliter (ng/mL). A PSA of 4 ng/mL or lower is normal; 4–10 ng/mL is slightly elevated; 10–20 is moderately elevated; and 20–35 is highly elevated. Most men with slightly elevated PSA levels do not have prostate cancer, and many men with prostate cancer have normal PSA levels. A highly elevated level may indicate the presence of cancer.

What Tests Can Detect Prostate Cancer Early? Still, a level below 4 does not guarantee that a man doesn’t have cancer. About 15% of men with a PSA below 4 will have prostate cancer on a biopsy. Men with a PSA level between 4 and 10 have about a 1 in 4 chance of having prostate cancer. If the PSA is more than 10, the chance of having prostate cancer is over 50%.
